RSS Mixer

I found a cool stuff to manage multiple RSS subscriptions -RSS Mixer. I tried it with my three sites to produce this single RSS feed for all my stuff, and here's the resulting link: http://www.rssmixer.com/everthing_rwcutter.rss. The resulting mix can be saved for web pages, iPhone and widgets. If you're subscribing RSS feeds or you need a simple RSS address for your friends, try it.
