Not there, LA or Boston? No problem. Subscribe to twitter feeds for #hashtag searches or a "daily" paper.li for the feed (or create one if none available). The main page of the MLA site is running a live feed. Many presenters and some panels are tagged. Every hashtag generates an RSS feed. As I type, presenters and attendees are diligently blogging and tweeting both MLA and AHA conventions. Tweets can and often do include links, some to blog posts.
This model holds for just about every conference, regardless of acronym but depending on prevalent communication technology habits and saturation.
Hashtag searches for cross disciplinary fields such as #DigitalHumanities will yield results from multiple conferences. #NewTools (a session in the Academy in #HardTimes initiative) opened up participation taking questions by tweet from followers not attending IRL. Wish I'd known about it.
MLA member or not you can search session listings, some annotated, online by participant, subject or meeting type. Non-members can register as guests, no commenting but you can still read member posted comments
