Make webmasterworld our customizable, one-stop information source.
Customizable homepage like those offered by major portals: rss widget, top threads, threads I've flagged for following, summary of latest items added to informational sections (ie user blogs, articles, news), personal to-do list, etc,etc.
Make it so that I only have to visit one website with my morning coffee and get my information at a glance. If that site is Webmaster World, then I get interesting industry-related conversations at the same time. I need to be able to put things where I want them or eliminate them if I don't care.
A real sense of community would help: user tips, user created widgets/code samples/software - open source the community. The internet has moved to a user-content-creation model, don't fight it.
