Is it possible that for some of us, this site may be perpetuating our situation? Do you think some people would much rather read about losing weight than actually do the work to lose weight? I'm wondering if we spent less time being social and supportive and more time busting our butts...
I'm sure that holds true for a lot of people.

Sort of related: There's a blogger whose weight loss blog I have followed for a couple of years. She has a significant amount to lose and she keeps yo-yo-ing the same 20-30 lbs over and over and over again. Her blog posts cycle between bemoaning her latest binge and how she has had this "realization" about herself or her eating habits or her life or whatever ... and how *that* will make the difference and she's got a whole new outlook ... and ... and ... and!
After reading her blog for 2 years, I've stopped commenting or responding or encouraging because I've begun to get the feeling that she gets more out of the talking about it, than she actually gets off her butt and does all this stuff she talks about. I think there's probably an element of enjoying the attention and comments of her regular readers as well. I dunno. I'm not trying to judge her - but I've realized that her blog is less useful to me than I thought it was when I first found it. It's now entertainment rather than informational.
So I think it's all related - blogging, message boards, etc. I think there are a lot of people who feel like they're Doing Something (in the great big "I'm doing something about my weight." sense) simply by reading and posting.
I think it's kinda related to the whole buy a gym membership and never go thing: I bought the membership, so see .. I'm Doing Something about my weight.
Or buying into a diet plan or book: I bought the South Beach book (although I haven't even so much as read the intro yet), so I'm Doing Something about my weight.
All of that said, I do think there's a HUGE benefit to the social/supportive part of it. I know for me, I lose weight better and faster when I'm accountable (in some way) to people - even if it's a bunch of strangers on a board. Having the monthly challenges and games to give me something to aim for.
And, I'll admit there's an element of walking the walk. I give a lot of advice here and if I can't do it, stall out on my loss, gain weight back ... then why should anyone listen to what I have to say? So opening my big mouth as much as I do (

) keeps me accountable to me in a lot of ways. It's a big time put-up-or-shut-up for me.
Just my rambling thoughts on the subject.
