If she keeps at it, she will do a successful product, too.
I was a huge fan of Pownce, Motion, LeafyChat, Baconfile, Convore, and Grove. All failed.
I was really hoping this one would work, but after seeing no improvements in a year, it became obvious it wouldn't. :(
But huge props to Leah for keeping at it... I'm disappointed at the haters on this thread taking personal pot-shots, instead of recognizing that her record shows an admirable perseverance and a true passion for building better messaging technology.
..or is Campfire/HipChat/whatever-else-is-left "good enough" to make it not worthwhile?
Those that don't give a fuck are using Campfire/HipChat.
Those that do give a fuck are usually hosting their own IRC.
Find a way to squeeze out both and you have a potentially nice business model. (Hosted IRC + nice web clients for paying customers?)
I guess we'll be looking at hipchat and some of the other alternatives posted here.
