There's been an update to the post:

"Updated: Yet another source says the acquisition discussions are still fairly early stage, and the two companies are also considering working together on a Google real time search engine."

So there is new Google Real Time Search Coming, thats So Kool :)

It's funny to think about those ex-googlers working on Twitter being working again with the big G! :P

Google and Twitter are in talks, but not for an acquisition, just to allow Google to better crawl and index Twitter...
