- Too distracting. I used it most when I was working to have music on in the background, but if I wanted to participate I was constantly tending to my playlist. Not sure how to fix something like this.
- No way to explore music outside of going into rooms. It would have been great if they had a "Top 200" tracks or a way to browse genres (just add in an option when you create a room to select a genre and have other for the fringe categories).
- Saving music sucked. Yes, I could save stuff to other services, but the experience of doing so was daunting. For example, I love Last.FM, but taking me to the song page of the track that's playing on Last.FM is pretty weak. Why not stronger API integration? I heard a lot of music that I would have loved to put into a list, but the functionality wasn't there.
- Becoming a DJ in any room with a decent crowd was damn near impossible. People would hover over their mouse to get that coveted slot. If I started my own room, you'd only get a handful of people to come in. The point here I guess is that it would have been nice to have some better promotional tools so people could discover different stuff. Sorry, but I don't want to listen to dubstep all day. Woh woh woh wee woh.
Easy fix: fix your features and add in some cool stuff. Send me an email or two telling me to check out something useful (not "we added in Facebook!"). I'd come back in a heartbeat if some of the stuff above was fixed.
