I am an avid reader of the Consumerist http://consumerist.com, mostly it is for kicks, but it does keep me in touch with some of the things happening in the US. I first became hooked when having problems with Bank of America and a reader directed me to the Consumerist for help.
Today, I came across a story that is really worth sharing. It is the blog of a young man who is losing weight. Essentially, many of us have been there and done that, but this is an example of how technology can create a support and motivational system. You can read about it for yourself here.
