You are over estimating his influence. I'd be surprised if Daly gets more than 50,000 hits for a race.
It's not about influence. It's that he's the go-to guy for commentary about television coverage. Most people I talk to online and on the phone enjoy ESPN's coverage -- but you go to TDP and you see his complaints about ESPN followed by hundreds of complaints from his followers... really, his followers it's kind of like conservatives watching FOX News or liberals watching MSNBC. I enjoy going to TDP to see what's coming up on NASCAR TV and he usually has the NASCAR and ARCA TV schedules up. But he has never had and will never have anything nice to say about ESPN.
He has some influence, but the mainstream motorsports media sees his complaints and his followers complaints and think that is the norm in NASCAR media because there's nobody else out there saying otherwise until lately. Pete Pistone has always called him out (not by name) but he's really stepped it up lately, as have a couple others in the mainstream NASCAR media.
I used to like what he had to say... then he praised SPEED endlessly for their atrocious ARCA Racing Series Danica Patrick 200 coverage because they focused on Danica the ENTIRE race -- the very same thing he bashes ESPN for. And every week, he seemed to praise SPEED for the Truck Series coverage while most fans I talked to were complaining about it. Then he bashed ESPN endlessly -- no merit, just complaints about the camera zoom-out function not being used (actually it was).
The final straw for me was when he blew a gasket over ESPN not cutting off a college football overtime game to go to NASCAR Nationwide Series Countdown. I pointed out that many fans would've kirked out if the race was cut off for College Gameday. He started saying I have no idea what I'm talking about. And then everytime I said I was enjoying ESPN's coverage, he'd say I was delusional and that I have an agenda.
Homestead, he complained that they were focusing too much on the Chasers. I told him to look at the 1992 Atlanta 500 and that it was the exact same thing -- he again went in to this "you don't know what you're talking about" shtick. Actually, I do, you can watch the entire race on Youtube for free.
The fact that his blog magically appeared when ESPN took over in 2007 is no coincidence either. I won't say why but I do know the reason -- simply put, he has an axe to grind with ESPN and I'm glad Pete Pistone and many others are starting to call him out.
