Interesting thought and one that had never crossed my mind until I read this article from Kuno Creative Strategic Marketing. They assert that Twitter is quickly replacing Google as the go-to place for valuable information. Of course, this should all be kept in perspective: Twitter still has a relatively low number of users, at 7 million, compared to Google's massive worldwide reach.
Their point is interesting though. They concede that Google is still "king of meta data" but go on to say that it is just too massive and people really can struggle to find relevant results and therefore go digging through the pages, wasting alot of time. Hmmm, I've done that a few times, how about you?
Twitter, in their minds, is like a search engine that is full of people with similar interests to yours, whether it be marketing, software, supply chain, medical, etc., giving you direct access to the 1% of the information Google would give you but without having to go through all the other "junk." Twitter is indeed full of "gurus" who are the best of the best at what they do and they are constantly feeding a steady stream of information. If you go to search.twitter.com and type in what you are looking for, you will get a very relevant, quality list.
So while Google has everything, Twitter may be able to save you some time searching for it because it is smaller and a lot more personal. Give it a try sometime.
