Also, even if MacWorld moved entirely online, it's not like its web site is one of the only places to find this info, as the print magazine was in the 1980s. A lot of news organizations that are fierce competitors now simply didn't exist a decade or two ago. Hence today's major layoffs as opposed to reassigning the existing staff to the web. (When I look at the Recent.io knowledge graph, the top of the list of news organizations that cover Apple includes: Fool.com, Cult of Mac, Silicon Alley Insider, BGR, and TUAW.)
I wouldn't be surprised to see MacWorld with legacy costs and pay structures that make it less competitive against these upstarts.
Some of the ex-MacWorld journalists who are freshly unemployed are looking for jobs, so if you know of anyone who's hiring in this area, I'm sure they'd appreciate the pointer: https://twitter.com/PhilipMichaels/status/509752573763407873 https://twitter.com/jsnell/status/509749300683735041 https://twitter.com/danfrakes/status/509756139831975936
While there are far more people using Apple devices, there are also much larger support communities for them as well, so a printed magazine is largely redundant.
This is unfortunate, but that's the nature of publishing in this newfangled media landscape. (As they say.)
On the contrary, look at the core demographic of a tech magazine to begin with: people obsessed enough to buy an entire magazine about one company's products. Add to that that that company's devotees are tech savvy and want the information yesterday, and you have a recipe for disaster for a magazine that comes out a month later with info.
If you're into reading columns and opinion pieces, there are much better blogs and sites, e.g. Daring Fireball, Roughly Drafted, Recode.
If you're looking for detailed reviews and specs there are again much better blogs and sites, e.g. Anandtech, Ars Technica.
And if you're looking for rumors, there are yet again much better blogs and sites, e.g. AppleInsider, MacRumors.
And there's Twitter, and HN, and what not for live coverage of news events.
And their site's redesign made it slow as hell on low-end iDevices.
In short the site brings little to no value to the table. Or then I'm too young or too old or too dumb to understand what that value is.
