Wesabe closed down recently and they did open source almost all of their code. I think that speaks well for their main backers, OATV and Union Square.
Odeo struggled for five of the seven months I was there. I think it was pretty clear we were a bit lost and the board was very kind about it, i.e. they knew they weren't going to come up with the the innovation that was going to turn into a big success. George Zachary from CRV was the primary guy there. I like him personally a lot.
For some reason I feel like the board gets crazier the more success you have, in other words they're not going to fight with you over how you lose your last $100k, but they're damn well going to fight you to make sure you don't blow your $100M valuation. I don't have much more than anecdotal evidence for that though.
