Hubski keeps me coming back for a number of reasons.

1 - learn stuff 2 - discuss stuff 3 - share stuff 4 - share my own stuff

1 - there are some smart people on here that I DON'T agree with. So their intelligently submitted material expands my brain and helps inform my opinions and decisions. I can't be one of the bobble heads who just glues himself to fox noise or slate.com just because they regurgitate the things I already believe

2 - similar to the point above - All of the different points of view here round me out. Ground me. They reduce the amount of "us and them" speak in my mind and in conversation. That may sound a little utopian or something, but it's true.

3 - I don't live near many of my closest friends. Hubski is a great way to metaphorically elbow the guy next to me and say "check this out". And through sharing stuff, I have made some new friends online. It's far more social than I expected it to be, and that's delightful.

4 - Shoot... it's basically what mk said. It is a great platform to share stuff. i have written short stories, shared short films, pictures, and art of my own creation. It's a great place to get good, hard, honest feedback without the false praise, and more importantly, without the mindless trolling.

5 - I forgot about the donuts... I'm still waiting on those donuts.

welcome throwaway. Who knows, you might dream up an entirely new use for hubski...
