I started to yesterday. It's more personal and I will work on filling up my profile more & more as i go along. It's a form of social media like instagram or anything else.
I don't care if people do/don't know what I look like, and my avatar is more for my own interest than anyone else's to be fair. Used to have my own face on there for a while but I get bored of seeing my own Minene-san > Alex
