I’m pretty active on Tumblr and think it’s better than Instagram. I use it more anyway.
YouTube is a fun outlet for me and I use it to post reviews of camera gear and bags. I have too many of both.

Redbubble – I sell a lot of stickers and shirts on RedBubble.
Etsy – I sell a few stickers on here occasionally. Very occasionally. You’ve heard of people making a living on Etsy? I’m not one of them.
