How else are you gonna pay for the ACM membership? ;-)

Really, it's a matter of making time for reading and learning. Pick up a paper sometime at night when you don't feel like coding and would otherwise watch TV. Or print it out and read it on the subway or carpool.

You also mentioned Cormen being too hard for the "average developer" and covering stuff you didn't learn in college. Cormen is intended as a textbook for later undergrads or early grad student courses. If you didn't learn the material in college, Cormen is your chance to learn it. And you have to treat it just like you're in college again - really, you can't expect to just magically know things. The whole point is to learn from it - if it covered stuff you already knew, there'd be no reason to read it.

clarification: Cormen is wonderfully easy to read, relatively speaking. I learnt from Automata Theory, Formal Languages, and Computation, by Aho, Hopcroft, Ullman. That was hard :)

They made ACM with digital library close to $200... ugh.
