Hard to find nice and bug free open source

OpenSource's problem on sourceforge is there are too many projects. Myself also getting confuse to determine which one should he/she give a try. me sometimes also got difficultly to try a new open source application that have very good feature but in fact, These programs are good in new experimental features but always come with bad interface and bugs needed to fixed. I hope there would be a website that post productive OpenSource application. So the open source hardcore users can insert their reviews and give less times try to find a program that satisfied user.
