I'm lucky. I get my subscription paid for because I'm a Debian developer (one of the few perks of the job).
Would I subscribe if I had to pay for it myself? After having been a subscriber for about 2 years, and for $60USD per year, probably yes.
LWN is one of the few weekly publications that I make a point to read. I find the writing style, and the length of the articles to be quite good. I think most "political" issues are covered fairly objectively. It's a good read.
I also subscribe to Linux Journal in dead-tree format, and to be honest, I have about 6 months worth of magazines lying around the house at the moment, still in their plastic. Purely because I just haven't had the time (or the presence of mind when I have) to sit down and have a read of them. And that's not because I don't think LJ is a good publication, quite the contrary, I think I'm just satisfying my information requirements with LWN, and so I'm not finding that urge to pick up the magazine.
I personally wish Jonathan all the best with LWN, and hope to see it reach 10 years. If you like what you can read for free, and would rather read it hot off the press, consider subscribing. If you're a Debian developer, you've got nothing to lose.
