Reality is a bitch!
Really sorry to hear about the end of Linux Journal - it was a quality mag in a world of quick answers via Stackoverflow etc.
That is the real problem - we live in a TL:DR world, and the people who are still willing to invest time in reading depth are few and far between. They are also not people who spend money, free beer is what brought them to Linux in the first place!
What LJ should have done is to sell their brand rather than their words - Get their logo on the talking circuit that makes up so much of the vacuous world milking Linux - because that is what the reality of Linux is these days - a few people write some genius, and everyone else starts selling the potential, style over substance.
Not that any of this really is news. Stealing BSD code is what actually built the internet, all that has changed is the lawyers have more complex licensing to get paid to play with.
