I like the name, heres why...
like the title says, I like the name for the reasons below.
Unlike registering a year like 2010, 2011, or 2012. The domain is never out of date, because there will always be a next year!
As far as how to develop the domain, the diet idea is good, but it can be so much more. What goals do you want to accomplish by this time next year. It can be losing weight, business goals etc.
It could also be used for a prediction site, what do you think will happen next year. What will the economy be like next year, sports-who will win super bowl, world series etc.
You have a good domain to build on, but it will take a lot of work
Not much value now, but a lot of potential!
