This is an example of a marketplace listing in Flohmarkt.

What "I" did here...

- Went to the "All" tab over at Flensmarkt - Much like PeerTube, there's a Home, Local, and All tab, the latter of which includes items from other instances that you've manually federated with within the radius you've specified from your location.
- Next, there's a choice to make if you're interested in an item. You can register for a local account (I don't see any reason to do that unless you want to post a listing on that particular server), or you can remotely add yourself (like I did). Since the remote features don't quite seamlessly work with Mitra, I tried this from a masto server - no joy. I tried it from another masto server (a masto fork) - no problem this time, even on an older version of masto. That was humorous to me, as I've a bit of disdain for mastopub servers and found it amusing that even some of the instances running the very latest version of masto won't work, while older one's based on forks do; but I've got a twisted sense of humor.
- So next, you can engage with the seller directly from your local instance on most Fediverse platforms (support is added for various additional Fediverse platforms all the time). In this case, (visible because I chose the "All" tab), the particular item was from yet another #Fohmarkt server elsewhere - this is a very nice feature, like #DeSoc #eBay!!!
- From there, once you boost the item in the listing, others can see it in their streams, boost it further, make arrangements directly with the seller, etc. Kinda Kewl.

This is different from how most other attempts to deliver a marketplace into the #Fediverse. Usually, what I've seen is someone trying to integrate the functionality local to a platform, which networks (via ActivityPub federation) only with other like platforms. That's not a Fediverse solution - that's a platform solution and leaves everyone else on the fediverse not running that particular platform disenfranchised.

For example, using the Epicyon server platform as an example, it is first to be understood that this particular server platform is designed for very small numbers of user accounts per each instance. You also have to manually contact the admin of remote Epicyon servers yourself (or be contacted by them), then mutually agree to federate each other's marketplaces separately and distinct from any wider federation configurations your server has. Considering the inconveniences with locating other Epicyon instances that may or may not have enabled and made use of their marketplaces and establishing a mutual publishing agreement, coupled with the likelihood that each of your instances between 1 and 10 users, posting an item in the marketplace has a pretty high probability of being more effort than its worth - especially since it dosn't federate with any other Fediverse platforms.

Others follow a similar design, but also generally operate like normal #ActivityPub federation using a blacklist method, as well as being able to accommodate potentially hundreds, or even thousands of users per each instance (yeah, I know, semi-monolithic); so even if those marketplaces didn't already automatically federate across the Fediverse with all instances of other like server platforms, it's still a huge improvement over the previously discussed smolweb platform's model.

But they're still not Fediverse wide...

This is where Flohmarkt really starts to shine - it's fully Federating (Still a WIP wrt some platforms - see the wiki for particulars) across the entire #ActivityPub portion of the Fediverse.

You can check for the latest particulars on Flohmarkt's current Federation status if you're interested in your particular Fediverse platform and level of interoperation with Flohmarkt instances.

I do have some criticisms of the particular functionality in federating that the developers have chosen to incorporate, however. Basically, The server admin still needs to manually federate item listings between the local instance and other remote Flohmarkt servers. It doesn't need to be this way however, but one must concede that after going over the documentation and seeing that the concern's of the dev team are over unchecked spam, phishing, poor quality ads, etc., I find it to be a very reasonable concern, although I'm still not comfortable with how the Dev team has hard-coded this conditional into the server's capability, when a slightly different approach might afford self-hosters much greater flexibility and incintive for adoption; namely:

- Make the current model the default
- Enable other configurations for federating between other Flohmarkt servers (and eventually, other platform marketplaces) via either simple configuration files, runtime arguments, or via a GUI in an admin control panel, including that of an uninhibited fully blacklist model of sharing listings between Flohmarkt servers.

I generally tend to think that hard-wired, opinionated configuration choices are a less than ideal (usually bad idea) than acknowledging issues surrounding such decisions and then choosing a default while affording server admins (or users themselves) of being able to manage the options for themselves. This is one of those cases where I feel it could make a huge difference in the viabilty and adoption potential for this, "Strictly Federating Marketplace" Fediverse platform.

The other (very minor) criticism I have for Flohmarkt is the pin & string radius solution as it is currently implemented:

- It's determined by the server admin, instance wide
- It's determined by the server location, or some other arbitrarily decided locale

The radius is a great idea, but I think the following would go a long way towards improving the utility of this feature set:

- The server admin decides whether to enable user-level radius configs or server level, as is the case at this time.
- Local users determine, and have control over whether an established is applied to either their entire user profile's repertoire of items listed, or on a per item basis.
- If he user chooses a per item radius, each listing could have a different radius established.
- The local users have location radius specifications that can be based on different criteria, such as pinning a location on a map of their choice, by country (the free IP2Location databases can accommodate this behavior).
- The user's particular radius settings for each listing must be preserved and observed by all federating remote Flohmarkt server instances (but not by individual remote user shares/boosts, which should remain unrestricted).

This Radius feature is extremely powerful and I think that every effort of the development team to exploit the potential of this feature set should be a major consideration. Eventually, Flohmarkt servers will federate with other server platform types, exchanging listings between say, Flohmarkt servers and Friendica servers, etc.. but the awesome power unleashed through following and boosting capabilities that are already fully available to remote users to share with others holds the potential at this very time to make Flohmarkt item listings ubiquitous across the entire Fediverse, ... And that is really kewl :)

Well, I'd rather tease your interest and see you go checkout more for yourself rather than feed you everything you wanna know about a really kewl #social_commerce communications tool - you really should experience how kewl it is for yourself.

I couldn't locate a #Matrix support room for Flohmarkt like most contemporary software products maintain in the FOSS world, but the more traditional irc chan #flohmarkt at #LiberaChat is readily available, and of course, there's the issue tracker at the Codeberg repo I previously linked to above.

What are your thoughts and impressions on this novel approach to embedding the marketplace commerce structure into potentially everyone's social streams in the form of both a dedicated platform and as passive feeds via the intervention of other #Fedizens who share and boost individual items and listings in Flohmarkt?

I hope that helps! Enjoy!
