I've been stumbling through the changes at My developerWorks and learning the new tools and techniques. To help others like myself I've created a Wiki called "Getting the most out of My developerWorks." The intention is to have a single resource to guide people through a number of different aspects of using this network. It can contain documentation and tutorials about how to use the tools (even if they're just pointers to existing information elsewhere on the web). Ideally, though, it would also contain some guidelines about how to use My developerWorks socially... for example, tips for having a successful, active group; tips on keeping your blog popular; making My developerWorks and Facebook work together.
Please take a look and please contribute. I don't have all of the information, I'm just trying to make it easy to find. (If you could star the Wiki that will probably make it easier to find.)
