Fediverse

In addition to what others have said, PieFed is written in Python, rather than the highly difficult to learn Rust language, so new features are added roughly weekly rather than basically yearly.

Despite having been around for a LOT less time than Lemmy, it has already mostly eclipsed it in terms of features that people keep asking for. Examples include categories of communities, which are now user customizable and shareable, merging of all comments across all cross-posts (still distinguished which they came from though, and a link to their OP) to save those clicks and thus help defragment the Threadiverse, hashtags, etc. And those democratization of moderation features that I linked... even Reddit does not offer that!!!?!!! (it's goal being to make money, rather than offer an experience that people actually ask for and want to use)

Caveat: it does lack "polish" in many areas, as it is still catching up to Lemmy and Reddit (even as it surpasses them in some important ways). e.g. there is a Preview feature available when making posts but not for comments, and like Notifications will often fail to function properly e.g. point to deleted posts rather than be removed.

What will GREATLY help with the above is there are two apps adding support already. Interstellar is already available in the Play (+App I would presume?) Store, though still alpha level so also not polished yet entirely functional and the dev (as too with PieFed itself) very responsive. The other is a fork of the well-known and regarded (and FOSS) Thunder, but still only accessible via GitHub atm.

So TLDR of this TLDR: PieFed is a Lemmy/Reddit replacement that is in many ways better than those platforms, although in some ways not entirely perfected yet.

Personally, I use PieFed as my daily driver for 99% of Threadiverse tasks. I fall back to Lemmy rarely for things like its superior (atm) search functionality. Use whatever you enjoy, though I do recommend at least walking through the account creation process (even if you delete it later), bc it's really heartening to see that account creation wizard and how welcoming it makes coming to the Fediverse, whether from Reddit or Lemmy!:-)
