Blackboard, the horrendous courseware behemoth, has heard about this Web 2.0 stuff and decided the right response is to clone del.icio.us — as a closed system inside Blackboard!
I love the bit about how "limiting access to Blackboard users" is supposed to contribute to the goal of "a new way to find educationally valuable resources".
If only they’d put a little effort into opening Blackboard up, for starters by supporting e-mail and RSS subscriptions so students wouldn’t have to log into Bb’s nasty multi-click frames interface to keep up with their classes.
Ah — Googling a bit I see that Blackboard Scholar permits non-users to search its collected bookmarks, but only lets registered users create bookmarks.
It’s part of the Blackboard Beyond Initiative, which is at work on "e-Learning 2.0". Trying to read through the marketing murk, it sounds like the BbBI people themselves may actually have found that elusive clue; let us wish them success at revolution from within.
