It's bound to happen the more experienced and knowledgable you get about guitar playing. Sometimes I sign on and look at the threads and think 'jeez..I already know the answers to all those questions', and get frustrated that the question was already asked and answered a year ago. But the same thing happens with guitar magazines etc... one month I'll buy Guitar Player and learn something totally new.. other times I feel like it's the same stuff rehashed over and over again. You just have to remember that at one point, all this information was brand new to you too.
