Even if I'm just "the other Kat" to most people it's nice to be recognised. It's better than in person because you don't need to panic about getting a name wrong.
x-cutie-x-pie-x got me to join Mene from Gaia. I used to just lurk in her exchange thread and it took me about a year (if not longer) to feel confident enough to make my own. Just last event I managed to make a hangout in the event forum so after five years I might be getting there. I can't RP or do art or anything creative but people still have time to just chat and hangout.
(Psst, virtual keyboard is handy if you have broken/stuck keys.)
