Backgrounds are, IMHO, a bad example of everything needing to have a rule. I hate the idea of digging through them until I find the skill I want. Sometimes it works (I have an urban detective paladin who wanted streetwise), but a better rule would be:
Choose a skill that fits your background, subject to DM approval.
I promise I won't not buy books, WotC, if you just had the flavor text for backgrounds and one single, better, rule for them all.
But WotC did put a fairly standardized process in place for 'general' backgrounds -- the Phb2 Background Benefits section.
Nearly every single background benefit found from other sources -- including the Eberron and Forgotten Realms Players Guides and most especially the Scales of War background benefits -- are hands down more powerful.
Its an easy option to disallow all but the standard Phb2 model, if desired, but its annoying if you didn't identify the problem early on.
As fba827 said, I think the the 1) +2 to a class skill, 2) add a skill to class skill list, or 3) an extra language are nice extra ways of differentiating PCs.
Moreover, I also have the house rule for multiclassing which will give a character a +2 (instead of a redundant dud feat) if that character is already trained in the (single) class skill granted by the MC feat.
For instance, an Avenger taking Initiate of the Faith gets +5 from initial Religion skill training, plus +2 from the MC Cleric feat. That's on top of any background benefits or ability or racial modifiers.
IMC, most people do min-max like that I've noticed, but I don't mind. I require at least a page in narrative background before they begin.
