• directly on the (over 100,000!) publishers’ websites who offer a follow.it option
• in the follow.it directory 
• via the bookmarklet tool 
• by calling up the feed page on follow.it (such as follow.it/techcrunch) 
• by entering follow.it/ in front of the URL of the publisher’s website 

The best option is to encourage the publisher to offer a follow.it option directly on their site, as that makes following them very easy.
