ALA Midwinter

As I get ready to go to Seattle for the Midwinter meeting of ALA, I find that several librarian friends and colleagues have posted information about there whereabouts and schedules all over social networking sites. I have written a few of them but I have no idea whether they will check the messages within their different myspace, friendster, facebook accounts. I know that I will be too busy to check anything but my email. So, do you need to monitor all your contacts across all your profiles?
