Probably not, but no harm in trying. If nothing else, there's a bit of PR in in it for them that doesn't cost much.
@FoxBroadcasting is bringing Twitter to primetime this week, via repeats of #glee and #fringe.
Cast and producers from both shows will log on to Twitter during airings of both shows (which Fox has dubbed "tweet-peats"); those tweets will then be simultaneously telecast in a lower-third scroll on Fox.
Viewers will also be able to follow and RT (that's Twitter-speak for "retweet") ongoing commentary via the cast and crew members' individual Twitter accounts.
