If mobile learning interests you (you know, cell phones and the lot), then check out the new and improved mLearnopedia.
I was also introduced to Coventi this week, which is similar to Google Documents, but 1) it’s not owned by Google and therefore is not connected to all that other information about your Web life and 2) it features a chat bar. Think of it as a user-friendly wiki with integrated text chat. Conventi offers 3 roles – reviewer, author & owner.

Hi Harold,
I was passed on from a German weekly newsletter (trainerlink) to your blog! When I arrived here I’ve just found an interesting alternative to Google Docs – I will check it out! Thanks!
Hello from the U2-participant Angelika
Coventi, as of 1 Feb 2008, will no longer be in business.
