First of all let me get one thing straight – I like Twitterfeed. It’s a perfect way for me to publish my feed to Twitter.
The problem arises when people start to publish other peoples feeds to Twitter. For example the people who think automatically tweeting the Mashable or TechCrunch feeds will somehow make them appear popular or the Twitter bots whose sole purpose is to syndicate the Google News results for a query such as “internet marketing”.
If you are lucky enough to be in Google News all you need to do to get 50+ people tweeting a link is use a popular keyword such as “SEO” or “affiliate marketing” in your title and the tweets come rolling in. All totally useless.
Because Twitter has no way of filtering duplicate messages the search results (and aggregators like Tweetmeme) are polluted with dozens of identical tweets.
Twitter could fix this in an instant by removing Twitterfeed tweets from the search results or creating a duplicate content filter but they don’t seem to be doing anything about it.
