I resisted Facebook for what seemed like an eternity, finally signing up for the social network a year or so ago. In that intervening year I’d have to say that I now understand what the hubbub was all about. It’s a whole different way to communicate and share ideas—as well as photographs. If you’ve been resisting the social network for lack of a reason, here’s the excuse you’ve been waiting for: Lexar’s "Take the Next Shot" Facebook sweepstakes. It’s not a typical photo contest because the sweepstakes format means the winner will be randomly chosen from submitted photographs. (Maybe now I’ve finally got a chance!) Simply submit a favorite photo with a 15-word caption and be sure to become a fan of the company’s Facebook page, and you’ll be entered for a chance to win a NikonD300 or Canon EOS 7D, plus a lens, Lexar cards and readers. It’s a total value in the neighborhood of $3000, so don’t miss it. Enter by July 31.
