Even though I catch myself comparing Steemit to Medium or Blogger slash a Reddit, when I really think about it I don't really get the Reddit comparison.

Reddit has a ton of subreddits so essentially groups, Steemit doesn't have groups. Reddit is also in a sense a Q&A site which encourages people to chatt and come back. I drop a comment, I see someone commented on mine so I come back and coment back. It encourages community and interaction and discussion and Steemit doesn't really have that.
