I have noticed, in the last decade or so, a newer generation of collectors coming up who were weaned on soul/funk and are going out of their way to acquire it on vinyl.
It does amaze me to see people in their twenties buying the same singles I bought for 50 cents at Wax Trax Records long ago. I almost want to say, damn, where were these "soul kids" 25 years ago when I needed them?
The main difference I see with the younger crew is that:
(a) they all seem to think that reissues are tools of the devil (shoot, I usually buy originals and reissues about equally)
(b) they think $10 is cheap (well, these folks did grow up in the post-CD age, so I guess they have a different viewpoint of what a bargain is)
(c) they're a lot more tolerant of disco and "modern soul" than I am
