The awesome staff behind InformIT is receptive to suggestions on improving the site. I’ve been working with the Web Design Guide for a long time, so I have lost the perspective of a user visiting the site looking for information.
What changes would make the site more appealing to you? One thing that I think needs improvement is not having the sections broken into so many pages. Each section could be an entire page, or if it’s too long, then use pages (but not as many). I appreciate any valuable feedback you offer.
