Nice article!! I see they have a form at the bottom to apply to be on one of these.
Part of me thinks it'd be great to be an example: 60k salary with ~60% (gross) savings rate. I think it could motivate folks with average incomes. I also have nothing to sell...notice how many of the profiles on that site are for business owners who benefit from the exposure. But on the other hand...
a) I don't feel like what I'm doing is really that difficult or unique (probably tainted by viewing this board)
b) I don't think I'd want the possibility of friends/family/coworkers knowing this level of detail. I'd hate for them see it as bragging / preaching. I feel like it takes guts for these people to share full names, budgets, net worth, etc with the entire internet (especially if they're not writing a blog, advertising their business, etc)
