All the comments from all cross posts on a single page is great. You can also add your own user flair like you could on Reddit, which lemmy doesn’t support. I haven’t messed with it much yet, but the ability to make lists of communities into feeds also seems really useful.
I haven't used piefed myself but I wouldn't want to switch to it because I feel like it gives more power to downvotes and karma (or "reputation" as they call it):
Comments with -10 score are collapsed by default.
People who get downvoted a lot end up with a ‘low reputation’ indicator next to their name. You’ll know it when you see it.
Upvotes in meme communities do not add to reputation.
Those are three of the twelve points listed as differences to lemmy on their features page.
Yeah I'm not going to move to piefed for that reason either, I hate Reddit's Karma system, which is basically an ass kissing requirement to maintain social credit, though piefed takes it to the extreme by trying to exclude meme communities, to favor downvoters extra hard.
Also private votes seems like it'll be a nightmare. Good luck combating all but the most obvious vote manipulation.
The "low quality" thing seems... Kinda bad. If you mostly post in "low-quality" communities you'll gradually lose karma? That sounds like it's just punishing people who are more interested in shitposty meme communities.
I find a reputation system good, however it should use percentages instead of points to make it different than what the karma system in Reddit was. People are less likely to farm for upvotes when it can only show 100% max.
Afaik piefed does not really show the reputation percentage to anyone (I might be wrong), but just shows a "low reputation" when it is under a certain percentage.
tl;dr PieFed has different people behind it, a few more features, and is written in Python instead of Rust (I'm not a coder or an instance host, so don't ask me what that distinction means, but I've anecdotally seen more people saying python is easier to work with than rust than the other way around),
PieFed communities federate with Lemmy communities, tho, so no matter which kind of instance you're going through as a user you should be able to interact with all the communities (assuming your instance admins haven't decided to defederate with the other instance for some reason)
they had problems with transphobia from various lemmy instances, this is a way to limit that. which is being inflammed by right wing propaganda targeting an outgroup.
