The biggest problem with Gab (for me, at least) is that a lot of my old posts (even if they're just a day old) disappear from my profile page, and then if I'm lucky, they reappear again a few days later. (Here on NCD I don't seem to have that problem.) I don't really understand how this works, and why it happens. But I still reach way more people on Gab than on the fediverse, so it's a good place to share my memes, news articles and political takes.
