I'm a relative newcomer, so I don't remember a time when Head-Fi wasn't filled with recommendation threads. I actually waited until I had found something I liked before I joined up. I was more interested in being a part of the community and talking to people who shared my passion for audio than in pestering for information. I actually did my research as a lurker. I also came to help people, even if my experience is limited to about half a dozen different headphones. Within that total I've experienced quite a palate of different sonic signatures. Like nikongod said, I was trying to find my sound and, months after that purchase (my third headphone I spent a decent amount of time with), I've finally dialed it in. Grado was one stop on that path and I found what several people here said to be true: at least with the SR225i I found the genre bandwidth to be too small (and, interestingly enough, I didn't much care for rock on them!).
Like I said, I haven't really been here for very long so I can't speak to what Head-Fi was in the past, but I have come across what smacked of bitter resentment for newcomers quite a few times on this site. I guess on some level I resent that, but on another level I think I understand it. As I've spent time here I've noticed that some people just don't listen, and you the impression they're more interested in asking the questions and getting people to respond than they are in actually using the information to zero in on something that fits. This isn't just a Head-Fi phenomenon. One of our very best customers owns an aquarium shop and every so often somebody comes in and just asks question after question but never makes a move to buy anything. After a while he loses his patience, and I suppose that's what's happening with the older members. Maybe that's why many of them have given up and gone elsewhere. People who don't want to do anything for themselves and aren't really interested in advice but in a so-called "best headphone for $$$" can wear just about anybody down if there are enough of them.
