Twitter To Launch A Microblogging Search Engine

Google published a note explaining they are about to launch a microblogging search engine. That's a while we are expecting such a move in this business. Actually, Twitter made it easy for Google to access information. Now one of the main concern I have is that one of the most predictable business modell of Twitter would have probably gone through advertising, on an Adword basis. But now, Google, The expert of search engine, is taking away this possibility. Twitter could still post advertisement on Twitter account's page, but as Google is getting in the business, they excell in having contextual advertising posted on pages. I believe this is the first move for Google prior to a soon to be buyout.
