Good point! Just little blurbs work too, or talking about other stuff, the main thing is just connecting with people. Which... I don't really know how to do, but yeah basically I agree with this person. Also tumblr is great because if you feel up for it you can have asks which is a good way to share more info about the characters and stuff and build a bond/seem responsive to the community.
And I've reached my limit for advice, I know nothing, just what I've picked up from my friend on her own journey :')
