Searching Twitter can be frustrating and send you off on unexpected Internet tangents, which is why I welcome the practicality of Twoogle, a mashup site that provides side-by-side search results for Twitter and Google.
Twoogle's goal is to "make it easier to benefit from the real-time results provided by Twitter and the relevant sites" with the help of Google. If you ask me, it trumps Twitter's internal search because the comparison offers more relevant results and insight into the very hot topics of the moment.
