I always reinstall my linux setup from time to time, sometimes things just get too messy after you play around with new rpms and you know what to do.

I've been playing around with various repositories such as AtRPMS, FreshRPM, DAG, Dries and Livna. It's always a tricky business to pick the right repos to use in FC, because some of them does not mixed well. FC Extras seem to be compatiable to the rest. The most problem I found is Livna vs DAG/Dries/FreshRPM (soon RPMforge) vs AtRPMS. I didn't use other repos like Jpackage, Nrpm, and such since I do not need those rpms usually.

After some playing around, I think FC Extra + RPMforge provides the most benefit to me. I'm kind of scare of AtRPMS as it replaced a lot of libraries.

After that, I reinstall with a fresh copy and start using the repos for application. I just hate patchy installation.
