I've participated in Mudcat for a bit less than 2 years now, and, yes, it has changed in that time, at least in my perception. But, increasingly I find, when doing a search on some song or other musical question that has come to mind, that the answer to my search has been discussed within that two year period. Perhaps I missed it when it was current because I just wasn't interested at the time, which, of course, implies that I've probably changed within the past two years as well. What a radical idea!
