Tweets on Twitter, you can favorite them - but do people take the time to? It turns out they do and someone's probably been favoriting Tweets from you, too. Favstar is a new service that tracks the most favorited tweets tweeted and finds some pretty funny stuff that way. The service will also tell you who's been favoriting your tweets though - and tonight it added RSS notification to its features.

That means you can now subscribe to an RSS feed showing you who likes your Tweets, even if they didn't reply, retweet or respond otherwise. That's interesting information to know.

It's very simple to do. Just visit Favstar.fm, search for your Twitter username, then select the "recent" tab. Once on that page, your browser will detect a feed for your otherwise silent friends. Or you could just cut to the chase and subscribe to a URL like this with your username in it: http://favstar.fm/users/marshallk/rss

Right now the feed doesn't display the usernames of the people who favorited your tweets, you'll have to click through a notification to visit the Favstar site to see that. The site's creator wants to give people a reason to come back, and that makes sense, but I sure would like to see those usernames in the feed.

I've put my Favstar feed into my favorite RSS to IM alert system, just because I think that's where it will work best for me. I might put it someplace else later, but I sure am glad to have it; it's nice to know who likes your Tweets.

Why is this useful? Well, I had no idea that widely respected PR pro Constantin Basturea was thinking about me until Favstar showed me that he favorited one of my recent tweets. We haven't exchanged words in months - but his thinking of me makes me think about him. I know now that I could reach out to him about the subject of that tweet or some other matter and I'd already have a place somewhere toward the front of his mind.

If it's funny Tweets you're looking for, make sure to visit the amazing automated funniest Tweet finder Favrd, too. Favstar, though, has something for everyone who's ever been favorited at all. Now with RSS it can become a regular part of your social media monitoring, instead of just a fun one-off thing you check once and forget about.
