I am amazed that Yahoo is resorting to patent trolling tactics. Almost everyone in the Valley hates software patents, and only builds patent portfolios defensively, but they don't expect to have to defend themselves against each other. It seems very un-Silicon Valley of Yahoo to do this.

I think their brand will take a hit in the Valley. It's not the freshest and shiniest brand anyway, but still there is a long way down for it to go, and I think this will send it down some notches.
