I don't mind them. They add replay value for those that enjoy collecting them, and are usually pretty easy to ignore if you don't want to bother. That said, i can understand why certain groups of people might find them irritating.
For me personally though, i only really bother with them if it's a game i'm really enjoying (i do the same thing with internal game achievements, like the skill points in R&C). Otherwise i don't pay any attention to them.
