What happens when you pull a thread? You get a knot! This is a knot of Tangler Groups that is a little different than the other "Knots of...." in that the Folks at Tangle already have a directory structure in place for Beta Testing Groups and User Groups that are part of their "WEeb 2.0 Network Initiative"
Therefore, this Knot will simply be used as a pointer to the Tangler Directories and a list of the some of the popular related groups.
