Woody Windischman at The Sanity Point has written this great and extremely detailed 2-part “how-to” on the inclusion of a twitter- search scope into your SharePoint search results.
I do think this has great value, not only for Twitter items, but also the “twitter-for-companies” Yammer or alike..
You can really add some real 2.0 value with this, and it looks just great!
I don’t know how many companies will add this though..
