I picked up a domain and tested some things with it before dropping it again, 6 years ago. I picked it up again 3 months later when I noticed it had PR3 assigned to it(back when PR seemingly mattered). I built a solid informational site on it and it's still ranking well today.
I think many people have a similar experience and as Tedster pointed out... the bad sticks with a domain too.
