Have you ever put together that questionable 140 character outburst or ‘observation’ and then experienced ‘tweeter’s remorse’ when you sent the poorly designed nugget of wisdom? It’s like that e-mail you didn’t want to hit send on (those really suck though because in most cases you have no recourse other than to start putting together an apology / explanation immediately). At least with Twitter you have always had the opportunity to ‘delete the tweet’ but Twitter had an annoying little habit of keeping that nasty little bugger in their search index. That was at least until recently. TechCrunch reported

Now, when you delete a tweet, it will instantaneously be removed from Twitter’s search index as well. We’ve tested it out this morning, and it is in fact the case. Even better, those tweets are also removed from the search API. We’ve tested several third party apps, and none contain the tweets that I deleted.

There are two brass rings in search these days: real time and social. Google (and Bing) have been working on the real time thing with Twitter, and last week Google announced they were working on a Social Search option in Labs—and now it’s out.

With Social Search, Google finds relevant public content from your friends and contacts and highlights it for you at the bottom of your search results. When I do a simple query for [new york], Google Social Search includes my friend’s blog on the results page under the heading “Results from people in your social circle for New York.” I can also filter my results to see only content from my social circle by clicking “Show options” on the results page and clicking “Social.”
