iWeb stopped its evolution, what software to use now?

Hi,

Besides iWeb 11 I am wondering what software out there would do best to "take over" in terms of ease to use and nice result. I know iWeb 11 can still be used and build great websites but it will inevitably loose track with what is going on as development stopped since a while now, won't it? As far as I understand it (and correct me if I am wrong) iWeb generated files are not usable by any other website building software. Switching to another software means rebuilding all the site from scratch, wow that's a time killer! Anyway, before moving on I am looking to read from your experiences, your opinions and views about alternative webdesigning sofwares. I'm not much of a webdesigner but here is what I could put together with iWeb 08
