I miss the quality of the old posters. But that's probably to do with the fact that there were fewer regulars, so you got to know them...
It might have something to do with MacRumors being more fragmented now between Macs, iPhones, iPads, and iPods, the PRSI area, Community. It seems to be easier to "hide" by not going into other sections.
And yah, I remember a lot of the 2001-2005 folks that don't come around much anymore. I learned a lot from many of them.
