Almost as popular as the maid of honor or best man, the Tweetmaster or Tweeter of Honor is becoming a normal addition to bridal party lineups. This is a tech savvy person that can document your wedding from your perspective or just on your behalf.
It's quite rare that the groom is interested in anything having to do with the wedding planning aside from where he is supposed to be and when he is supposed to be there... Oh, and how much it's going to cost. Yup! That's usually when the groom's get involved.
Whatever style of wedding you and your fiancée prefer, as the groom you need to decide early on how involved you want to be in the planning process, and make sure your bride understands and is supportive of your role.
