Is Twitter Scaring Google?

There have been multiple reports that Twitter could replace Google. Twitter has quickly risen to become one of the most powerful sources on the Web. In 2008 alone, Compete found that the microblogging service grew 752 percent. Do you think this might make Google, the long-standing Internet giant, a tad-bit nervous or jealous?
Chris Brogan says, “…I think Google is a bit envious. I think they don’t know what to do with it all yet.”
Does this mean that Google is letting their feelings influence how they return Twitter results? There have been some rumors that Google may let the “authority” of Twitter users play a role in their results. For example, a celebrity or a well-known “authority” such as Chris Brogan could rank higher in Google results than an average Joe user.
Do you think Google is jealous of Twitter? If so, what do you think the company’s next move will be?
