Absolutely. It's easy to bash at Yahoo, but we can't forget that while Facebook (and many other players, including Yahoo) are using one hand undermine the "intellectual property" of other companies, they're using their other hand to try and protect their own IP using the same laws.

Take this absurd Facebook patent as an example

>System and method for dynamically providing a news feed about a user of a social network (US2008040673).

While the situation is different, as Facebook aren't suing anyone (yet), we can imagine if the roles were reversed, the story might be a little different. Why else would they file for patents if their intent wasn't to defend "their ideas."

If we're calling out Yahoo's patents as junk, we should be doing the same for facebook and the rest, otherwise we're turning a bad system of "who dunnit first" into an even worse one, a popularity contest.
