You know it’s spring when the temperature goes up, the flowers bloom and bloggers begin their campaigns to save their favorite shows in danger of being cancelled. With just a few weeks before the networks announce their fall schedules, the Web seems to have coalesced around “Chuck,” NBC’s action satire about a computer geek (played by Zachary Levi) turned unlikely secret agent. Fan sites like Give Me My Remote as well as online columnists like Michael Ausiello of Entertainment Weekly and Alan Sepinwall of The Star-Ledger have encouraged viewers to call upon NBC to give the show a third season.

Can the combined powers of the blogosphere rescue “Chuck” from oblivion? We asked the television producer Josh Schwartz (“Gossip Girl,” “The O.C.”), who created the series with Chris Fedak, what the future holds for his perpetually hapless hero.
