As a business owner I'd be VERY interested in something (fad or not) that cuts development time and complexity by a substantial amount. As a developer I want to use things that make my life vastly easier and lets me focus on the product rather than the programming.

Trying new things and taking risks can yield huge rewards! Of course it can fail spectacularly as well but for those that worry about that a lot, jQuery UI still exists!
