Is there any fediverse client out there (mobile or pc or web) that has support for multiple types of content, rather than just for one?
Most apps I find are only mastodon-like (including pleroma etc.), or only lemmy-like, or only peertube-like. One of the main benefits of the fediverse is that I could theoretically access all of those from one platform. But the clients I saw don’t seem to support it too well.
Yep, all this ^^^
This is also one of the reasons why I believe ActivityPub client-to-server failed and will likely never gain much traction. It either needs every single client to re-implement all the features it wants from scratch, or the entire ecosystem needs to be dumbed down to fit a single mold. Leave all the unique functionality in “uncommon” software like (streams) and friends, even software like Lemmy or PeerTube would likely be extremely difficult to build in a world where client-to-server actually became a thing.
The only way I can see C2S actually taking off is as IPC protocol between an “app server” (which would be the equivalent of Mastodon or Lemmy or (streams)) and a “federation server” which is just a dumb pipe that distributes and receives objects and activities, and even that has it’s fair share of concerns, both around efficiency and the same “dumbing down” problem.
