Sorry but I have to disagree with this. IME most PCs have 2-3 skills they are good at and no more. Many PCs have only 4-5 skills period.
Being a true
skill monkey covers a lot more skills with often much better modifiers. In the best scenarios, the skill monkey can offer help to the other PCs when the do excel, and other others can offer help to the skill monkey in every thing else (if they even can, of course).
Skill monkey PCs are actually my favorite type to play, so most of my characters have either some rogue or bard in them. In fact, the two PCs I am playing right now: a Barbarian/ROGUE and a Sorcerer/Warlock/BARD.
