never used reddit, but i like my kbin alt acc very much
xitter never really was my thing, neither masto or pleroma > but when xitter migration sped up last year, i thought that finally something is happening on the fedi, so i signed up at a calckey instance (and later, i got many more accs on other fedi platforms)
discord? no > matrix? no
yt: i use alternative frontends, but certainly not peertube
