It isn't a good platform for alt-media, nor as a social network. It discourages people from up-voting good content, because people want to save their "steem power". Instead of just liking stuff you like, people look at it like an investment. And it sucks as a social network, because it's pretty much all people you don't know, and will never meet. It's basically like facebook, without friends, and people only like and share stuff for monetary gain. The only people doing good on steemit are people who already had a fallowing on youtube, facebook, or twitter. Or people who bought into it. The vast majority of people on here are competing over the couple pennies they are going to get for posting a picture of their cat (no offence to cat people). I'm going to give it a try, but i don't see this site ever competing with the other major social media sites.
Anywho... That's my Two cents worth... Peace
