The new site is a lot better looking than the old one, and the navigation is much more simple and easy to use to find what you want when you need some info (apart from some teething problems with search). However, what if I come to the site looking to help others on the wiki or DiBo? There isn't any simple navigation there - I'm pretty much assumed to use a bookmark?
Might it be better to put some more prominent links to the community sites (i.e. top level of DiBo & Wiki) along with the feeds on the various technology pages, or even higher up the page tree? I couldn't even find a simple link to get to a DiBo view, just direct links to the posts in the feeds.
Also, what is the positioning of the major Qt focus here vs the Qt Developer Network that's currently in beta? (I much prefer the Qt DN site, even after this upgrade to FN I'm afraid - although it looks like this site cost a lot more, the Qt DN site is cleaner and simpler).
