Clive Thompson is a smart writer. Here, he compares Weight Watchers' online tracking system to role-playing games.
When I first used it, I thought it was like "Fantasy Football for dieting" -- you get a screen of stats and options and you manage them, hoping for a daily or weekly "win." (Of course, I wasn't smart enough to write it up and present it as thoughtfully as Thompson.)
As Weight Watchers continues to try to market the system to guys, they should consider that.
