A Technorati search hasn't picked up very much from this year's MLA in Phoenix so far, apart from Scott's postings.
However, Talis did organise a podcast involving delegates and others, which made me wonder if this might also be possible at July's Health Libraries Group conference in Eastbourne.
A correction: if I had used a more sophisticated and professional Technorati search strategy, then, as Michelle points out in her comment, I would have found hers and more.
Here's a list, and sorry for omitting you:
The Krafty MLA Blog (a collaborative effort involving four bloggers)
Professional Notes (Stewart Brower)
Michelle Frisque: Library 2.0
