Don't want to look a gift horse in the mouth and I still love the product, but Google Docs hasn't improved all that much since it launched. I loved Etherpad when it came out, then I was really excited when Google bought Etherpad... but they haven't implemented some of the basic stuff Etherpad had.

Still love GDocs and I'm really hesitant to complain about something I'm getting for free - but I do think they're playing with fire here a little bit if Google actually cares about the online document space. If they don't improve GDocs, someone's going to come take that market share from them, and Etherpad already showed a few easy improvements to make.
