88 speakers with Twitter IDs, 180 without - can you identify them?

There are fifty-three eighty-eight speakers at Lotusphere 2011 with Twitter ids (many non-speakers as well, of course), but the following two-hundred-sixteen one-hundred-eighty speakers without Twitter ids (and one abstaining).  Can you glance over the list and see any that you follow or whose ids you know, and let me know?  As speakers are added, I will adjust this list. Please help! (I have skipped those who say they do NOT use Twitter)
