Twitter's Promoted Tweets APR 13 2010
Twitter announced their long-awaited advertising model last night: Promoted Tweets. Companies and people will be able to purchase tweets that will show up first in certain search results or right in people's tweet streams. Which, if you rewind the clock a few years, is exactly the sort of thing that used to get people all upset with search engine results...and is one of the (many) reasons that Google won the search wars: they kept their sponsored results and organic results separate. It will be interesting to see if the world has changed in that time.
