One of the real joys of working in the web world is discovering the incredibly random sites that people make with your tools.
In the affiliate world, with eBay and Art.com, it was the super-specialized product sites. My favorite was the woman who scoured the globe for the latest in exotic hardwood knitting needles. She had quite a following; over 2,600 people per month subscribed to her newsletter.
For widgets, with Mpire, it was the product review fan-sites, like the guy who created a great-looking site dedicated to the BMW M3 and every possilble accessory for that model.
With SynthaSite, some of the fun, off-beat discoveries are the animal breeders who set up sites to promote their services and sell:
mini-lamas at http://Gingerichsminiaturefarms.synthasite.com/
parakeets bred naturally at http://thesanctuary.synthasite.com/index.php
leopard geckos at http://jandjleopardgeckos.synthasite.com/
cute shizshu / poodle crosses at http://puppylove4me.synthasite.com/
and many more ...
People's ingenuity never ceases to amaze!
