It's kind of old news now, but I do use Instagram and I'm happy to follow and be followed by others. It started as idle curiosity, and not really getting Instagram, but I've definitely had fun with it. In particular, I enjoy letting the Internet store and date-stamp images so I can look back and recall what happened and when. Much like a Facebook album.
In any case, my username is jlasala2112. And http://statigr.am/jeff_lasala is one way to just see it without the need for a smartphone.
