Since these search engines use different algorithms, even if Google and Bing/Yahoo both have parnterships with these major social media communities, I predict results will be slightly different enough to warrant both search engines to be used. What do you think?
The question now is whether or not Google will include Facebook updates as well. The Facebook deal with Microsoft/Bing is not exclusive, so Google could get involved if they wanted to.
Should be interesting to see how these "status updates" are going to be integrated.
From what I read, Google was in talks with Facebook to include them also but Microsoft/Bing sealed the deal (a non-exclusive one like the Twitter deal) first. But, as InsightsDigital posted under the post from CSCGAL about the Google/Twitter deal, there are privacy issues involved here that will require an opt-in/opt-out option.
