Jonathan Grudin and Dan Russell, two CHI and CSCW giants, are running the second edition of their mini-track at HICSS 40. The mini-track title is Using Information: New Technologies, Ways & Means, and they've got a blog up which includes the accepted papers for the mini-track (along with the Persistent Conversation papers) as well as pointers on how to have a productive time at HICSS. This is from Grudin, who is a HICSS vet, so it's well worth the read.
In case it's not clear, I highly recommend HICSS because you get access to some bigwigs in a relatively relaxed environment, and the acceptance rate isn't rediculously discouraging. Granted, it's expensive, but it's a nice starting point for beginning academics.
