In short, a lot of us don't want "a" magazine, we each want "MY" magazine - the one with a lot more of whatever we like and less of all that other stuff.
There is more being said here, but that is a good part of the comments.
I still like to peruse the edited, portable products of S&T enough to subscribe, and of Astronomy enough to buy occasionally. I enjoy the regular observing columnists and features and the surprise articles that are outside my bailiwick. With a 8-inch biggest scope and 50mm binoculars I feel plenty challenged by Sue French and other regulars.
I think the magazines generally feel less "buy new gear" consumption-driven than the web, since I can just flip past the ads when I know I don't have the money.
Web sites are also driven by advertising because someone has to pay for all this ( I will give my thanks to Astronomics here, both for CN, and for good values! ). Maybe the link to vendors seems more subtle here to some, because it's a click away, not a printed page advertisement, but it's still here.
CN often links readers back to older posts to answer questions - exactly like one complaint about S&T.
