RH/Fedora just came out with a magazine called "Wide Open" which just released its premiere issue last month. I bought a copy at Stinks-a-million and it was pretty good.... but of course, the first issue of any mag is going to be pumped up a little because they want to hold on to their brand-new readers. But hopefully they will have some good stuff in the next issue and it wasn't just a one-time thing, but I was pretty happy with their first issue. There was a nice discussion about security issues and pretty cool stuff in the tips and trick section.
