This pipe takes a hashtags feed from twemes.com, tries to extract meaningful terms from each tweet, uses those terms as the basis of a Yahoo search, and then changes the link of each tweet post to point to the top link returned from the search based on content analysis of that tweet...
...the idea being, if you click on one of the links below, it should go to something related to the post... sort of... ;-)

If the term extractor can't find anything meaningful in the tweet, the link points back to the original tweet on twitter.
