Even though I'm a big fan of being the first person to do something, there's still something to be said for copying another's successful business model, and adding your own twist to it.
A young man, Brandon Rowe, hoping to support his goal of making it to the Olympics, has taken the million pixel concept and tried a similar approach. Of course, it's been done again and again, but it amazes me that it can still work.
Link Experiment, uses link auctions to bid for placement on the page. There are 100 links total, and the highest paying links move to the top. He's got some rather big goals, including making one million dollars, and making it to the Olympics. Brandon has received nearly $10,000 to date with this site, which is nowhere near his first goal, but it's still quite a lot of money, and could help support him as he reaches for his second goal - the Olympics.
Recycling ideas may not work forever, but they can still be worth trying. Sometimes it pays off. I'll have to remember to try idea recycling now and then.
