Filtering out Foursquare and Gowalla Tweets with Tweetie for MacThursday, 04 March 2010
Gowalla and Foursquare tweets are annoying. If you're using Tweetie for Mac, you can add a list of "filter terms" that remove matching tweets from your stream.
defaults write com.atebits.tweetie-mac filterTerms -array "@gowalla" "http://gowal.la" "@foursquare" "http://4sq.com"
It's basically doing a string match for tweets that contain the above terms and excluding them from your stream. Really though, you can add any string of text to be matched and it'll get filtered out just as well. There's more info (and a few more examples) at the official Atebits Posterous.
