You put a shit ton of effort into it, you have every right to be proud!! 😁
It's a bit sad that Tesseract won't integrate PieFed soon, though it wouldn't be the first Lemmy app to forego that procedure. There's also a number of issues preventing PieFed from taking off as we all hoped, with multiple highly active people either migrating their communities off of it or not switching to it as previously planned. We HOPED that it would reduce tankie dependency, but in practice it doesn't seem to want to be a true "social media" replacement so much as something more akin to Mastodon, and it is actively even if almost silently pushing its own ideology more and more all the time lately.
Otoh, Lemmy development is GLACIALLY slow, plus they likewise push their ideology, and refuse to allow donations solely to code development without putting a heavy (though undisclosed iirc) amount of that towards maintenance costs specifically for lemmy.ml. So it's not like one side is demonstrably superior to the other there, just different flavors of the same - they'll each do as they please, regardless of feedback.
Thank you for all your efforts to make the Threadiverse more usable! :-)
