Most likely, it's because certain (possibly randomly chosen by keyword) forum posts get displayed on the front page of the MacTech site, which in turn also shows up in people's RSS feeds. That's a lot of eyeballs who just want to see what's going on. They don't respond because the target audience of the MacTech site are IT geeks and high-end users—which is decidedly NOT the demographic of these forums.

In short, "we bore the crap out of them." wink
