1. Public comments: I know this has been addressed, but I'd like to reiterate that it would be very useful for e-learning purposes to enable public comments on public Landing objects (be they blog posts, pages, or whatever). I don't pretend to know the technology issues involved, but inviting public comments would provide an important and different level of in-Landing learner engagement, and I think it would contribute to AU's accessibility mission as well.

I also mention this because for the first time my other blog is seeing some significant public participation for the first time, and I'm finding it really instructive and illuminating to monitor that traffic, reply to comments, and engage an unknown public audience.

2. Profile application options: The user profile page includes a lot of fields for displaying one's "username" for external account apps like ICQ, AIM, Skype, and Jabber—but not for Twitter, of all things. Maybe instead of three or four pre-set account app fields, could these be redesigned as un-set fields, each providing a drop-down menu from which you could select the relevant app you use? You could still display three or four account names, but the accounts would be set by you not pre-set by the Profile interface. (Again, not being a programmer I have no idea if this is even possible, let alone feasible.)
