You probably subscribe to dozens, if not hundreds, of RSS feeds in your reader. I don't know about you, but it gets a little overwhelming for me when Google Reader tells me that I have 1,227 unread items. If you're looking to quiet the noise (yes, please!) without hitting unsubscribe, check out FeedScrub, an awesome site in private beta that optimizes your favorite RSS feeds to show only the stories you want.

FeedScrub is pretty fabulous. All you need to do is create an account, add a few feeds, and start training FeedScrub to keep the stories you like and eliminate those that you don't. Since FeedScrub's service works nicely with Google Reader and Newsgator, once you add your feeds to the site, you can then add the tweaked feeds back into your reader and opt to continue scrubbing onsite or off.

FeedScrub works like a spam filter. So when you select to "save" or "scrub" an item from your reader or on the site, FeedScrub analyzes the words in the designated post and automatically discerns your future interests based on your saving and scrubbing behaviors. FeedScrub's personal training process for your feeds improves the more you use it. Make sure to subscribe to the Junk feed to ensure that you don't lose good content during the feed education process.

FeedScrub is in private beta, which means you need an invite code to sign up. Thankfully, we've got you covered - the first 500 people to use the code "mashable" will get right in. The free account lets you scrub up to 3 feeds, but if you really love the service you can upgrade to unlimited scrubbed feeds for 5 bucks a month.
