Listening to Rush was a real treat in the early 90s, because you when you heard the chainsaw rip into the Environmental Update theme, or the "Fierce and feminist" beat start, you had no idea what was coming next. It was great.
Many of us were online then, at GEnie maybe, or AOL, but there was no Free Republic, and few newspapers were online yet. Rush hit news stories that the local papers and newscasts didn't touch, stuff we had no idea was out there.
Point is, Rush had his sources then, and he has them now. The difference is that the evolution of the web has put many of them at our findertips as well, and usually before his show airs. Doesn't mean he doesn't do his own homework. He did just fine without us before FR came along!
Based on pictures of him lately I'd say he's checking out foodtv.com
