I'll give you a real life example. I was having some problems with facebook connection and posting. I searched google and all the posts from a couple of days back said that facebook had fixed the problem already. But a quick run to search.twitter.com revealed that many were still having the problem and it wasn't just me.

I'm sure once you see the results in your actual search results, you might see more value in it than it seems right away on the surface of it.
