Getting PS3 Cheats for Games

It seems that getting PS3 cheats in this internet driven world is actually harder than what it use to be. There isn't a really great place that you can find accurate and trustworthy explanation of cheats. Most of the cheats that I come across are either weak or of no importance. Do you think that the designers are just not designing enough cheats into a game? There are so many game studios today but a large market than what it use to be. I'm sure that schedules are tighter than what they use to be and designers don't have the same time to add little backdoors and cool cheats.
