Nah, I just have two because I've historically split my online presence up into these two usernames. Tbh I've just subbed this one to all of the same communities as the other one so it's largely pointless until things spread out a bit more, but if I'm posting about videogames I tend to do it under this name and if I'm posting about cross stitch I tend to do it on the other one. Eurovision goes on both :D

No actual practical benefit beyond it just seeming tidier to me lol.
