We're really excited about this new feature which allows anyone to
track concepts in real time over SMS or IM. Tell Twitter what words
or phrases you're interested in and you'll receive updates
containing those words the instant anyone Twitters them. One of
the most popular words being tracked by people right now is
"overheard." Send "track overheard" to Twitter to find out why.
(Send "untrack" if you change your mind and "stats" to get a list
of words you track.)
