The Brandon Hall folks seem to be making a foray into social networking. In concept, this seems like a fine idea both for their subscribers as well as for themselves. But I suspect they have clearly ticked off a whole bunch of their potential users by phasing out their popular Yahoo Group. I think it was a bad move to squash a successful email list to start with. Not to mention that it was a PR snafu to force users to move to their new social network. A number of subscribers to the yahoogroup have now formed a new group.
