I like the idea and initial basic implementation. I can see a lot of potential.

The name has problems, though. First, it seems a bit defensive: "Look, I did work!" Second, it looks/sounds a little like 'idiotwork'.

There are tons of themes and word fragments to work with for 'team microblogging of work tasks with metrics', so I think with a little effort you could have a very memorable, meaningful name.

Good luck!
