My Mega Site Network RSS - What I can do with it?

I have 7+ sites (covering technology, muscle/supp/steroids, credits/insurance, and funnystuff/jokes/flashgames) all linked in a giant 600+ items/day full content autoblog/rewritten RSS. I have already submitted it to any ******** RSS Directory out there and I have used RSSFWD to create mail that goes straight to Blogger/Blogpost blog (just one, don't feel like spamming, plus RSSFWD mails about 3% of all the output), and I am pondering what other uses there can be for such a feed... do you guys have any ideas? If so, let me know.

Forgot to mention a funny fact, Yet Another Related Post plugin for Wordpress also injects into the RSS, which officially quadruples the amount of backlinks per RSS item... just had to let you guys know how useful it is.
