Social Media - How Many Frontiers?

Since I've started to paint more seriously, it's been difficult to decide the best way to show off what I'm up to. Honestly, it is really tempting not to show anything at all. I feel like such a beginner again. But after reading Austin Kleon's book, Show Your Work!, I know that I need to show the paintings. All of them. Even ones I can see mistakes in. (Which would be all of them. But I don't think any painter is truly satisfied... ever.)

I have determined that I don't want to show every painting on this blog. If feels a little spammy to me. So instead I've opened up a tumblr account and I've been posting my work there.

I'm still figuring out how this blog and instagram (my other haunt) will work in the grand scheme of things. Questions like how much cross posting do I want to do and how much time do I really want to spend online are being puzzled out.

How has everyone else decided what to share and where?
