I recently came across an interesting article, Twitter and Local Search: A Status Update, by Michael Boland, Search Engine Watch. Michael conveyed the idea that Twitter search brings structure to all the noise on the Web with an index of real time conversations. I agree and now, at times, I get better results on a niche topics such as SOA or Agile development through Twitter search than through Google.

Michael points out that while Google spiders are quick to index new content, it still takes hours or days rather than seconds. He adds that's perfectly okay if you're researching a new flat-screen TV, or the history of Mongolia.

But it could be less effective in emergency situations or where to get the best pizza in San Francisco. Twitter search covers conversations, while Google search covers topics. When do you use Google search and when do you use Twitter search. What has been your experience?
