SolidWorks Corp is doing something well. They are taking advantage of current and relavent networking technologies, such as Twitter (search #SolidWorks), to promote the software and its users.  In fact, SolidWorks Corp has a substantial online presence. Some of this is their own doing, some of it by users stepping forward on their own. There are a multitude of outlets for information and support. There are forums, blogs, resource sites, networking sites (such as Linkedin and Facebook) .
Even with all this, there are still other interactive online resources. Who’s checked out the SolidWorks Wikipedia.org article? I recently made a minor edit to that article. It can certainly benefit from many more edits. Or, who’s checked out or contributed to SolidMentor’s Solidwiki? This is on Ben’s site. He also has the SolidJott SolidWorks add-in, which is growing rapidly in popularity. What are your favorite online interactive sites?
You’ve pretty much hit on all of them. I’m active on LinkedIn, Twitter, Facebook, 3 or 4 forums. It’s amazing how much more available information is these days.
