Foster does see a definite potential upside to blogging about weight loss, though. He said writing or reading a blog could be especially helpful for anyone who has been stigmatized because of their weight.
No one knows this better than Kenlie Tiggeman, the 32-year-old political strategist who fired up the blogosphere last year after she blogged about her experience getting kicked off a Southwest Airlines flight for being "too fat too fly" -- twice. By the morning after she posted her thoughts about the first incident, twitter had exploded with angry words for Southwest and her website Alltheweigh.com was flooded with messages of support. Within hours she got a call from Southwest headquarters, offering apologies and vouchers for free flights.
"I'm sure they never would have reached out unless I blogged it. That's how I got their attention," she said.
