This product may be a bit of a head scratcher if you aren't an active twitter user, but it will make sense if you are. The idea is that you 'sell' a bit of digital merchandise, or access to a web service via the 'payment' of a pre-prepared tweet lauding your service and tweeted to all of the twitterer's followers. The twitterer is able to edit the message but not the url. The service is designed to create buzz for your digital wares — a bit like women paid to frequent bars and tout particular tipples. Given that Twitter users are supposed by many to be taste-makers, it might be a good idea to try and start a few ripples with that 'community'.
Now that the online set are encouraged to blog, tweet, update, share and otherwise communicate like maddened rabbits, anything that makes that process easier is very welcome. Twitterfeed takes the rss feed from your blog and automatically posts to your twitter account and also to LinkedIn. Works on every major blogging platform.
