Wow, that John Stone Fitness site was WAY cool! And if I had learned of it right when it started, I would have followed his progress.
A couple of similar blogs are
Woolgathering, where Elizabeth Perry determined to learn to draw, so she posted one drawing a day. I do visit her blog every day; she's always trying new techniques, and her drawings are enjoyable to see. It feels like visiting with a friend.
and
Little Brown Dress. Alex Martin decided to confront consumerism, so wore the same brown dress every day for 365 days -- the actual one dress, not just many of the same style. The project was finished July 7, 2006. I was fascinated by this performance art.
Can you tell I'm not I'm not a techie?
I also heard on NPR a man who wrote
One Song Every Day... I guess there can only be so many of those type, though. Like the woman who started a
site asking for donations to get out of debt, that will only work once. I've heard of others... someone going through and making every recipe in The Joy of Cooking, etc.
What are you passionate about? What would you like to learn, but are afraid to? Listen to that inner voice... I think the most successful blogs of this nature are done because the person felt an inner prompting, and they grew through their explorations. Successful in terms of views, buzz, etc. I don't think many of the ones I mentioned had a lot of ads! But because of Elizabeth Perry's blog, she has gotten commissions to do artwork, so she *gets paid* to explore this side of herself.
Best of luck ~
