It does, but it's not nearly done if it's going to hope to compete with Twitter and Facebook, which I think it could do someday. For instance I would really like to see better embedding code for images, videos, etc. and a better default theme. One of the most exciting things about pump.io was that it used oauth to integrate with a couple web games (openfarmgame) so the game could put updates on your feed. Ton of potential.

I may sound like I'm complaining, but it's really just because I think it's so great. I don't feel entitled to EvanP's time, it looks like he's busy with a startup so I don't blame him at all.
