I do think it's amazing what Steemit has done, its incredibly hard to build a community and keep any decent number of people engaged so that's a big accomplishment.

I definitely think Steemit needs groups and private messaging and what not because as it currently stands if I wanted to chat with you I have to find a post of yours and leave a comment publicly, and on a post that's not really related to my comment. I know there's steemit chat groups but honestly I can't be troubled enough to have to hop over to another platform just to chat.

I know early on some people were starting to use Steem for commerce and selling things, would be cool if like a Steemit eBay type deal popped up
