Yes, aborting iWeb was probably the biggest mistake Apple has made for a long time. I have yet to understand why, and they didn't care to tell us, either.
I have 12 different web sites that I created with iWeb. To build those 12 without iWeb would have taken me months instead of hours. The simplicity and ease was incomparable. iWeb was the utopia for non-programmers. You never had to touch that ugly html, ever.
After trying every other web software made for Mac, I did land on EverWeb. It is about half as easy as iWeb, and it does require the individual to have to learn how remote hosting works (I never had to worry about that with iWeb). EverWeb wants you to let them do this, but at a price, and they also make you re-pay every year just to use their software.
No, it does not allow importing of iWeb. No others do, either. You have to re-do all your web sites in EverWeb from scratch. But, the nice part is that it works a lot like iWeb, and will only require a very small learning curve. It is mostly just a cut and paste process. But it will take hours for each web you move.
It is acceptable, at best, but no where near as quick and easy as iWeb. You have to remember, though, that it wasn't just iWeb alone. A lot of the ease was due entirely to paying for "Mobile Me" which automated all of the hosting and setup of your website. This attributed to the simplicity of non-programmers creating web sites with ease. Truth be known, the demise of Mobile Me is probably the reason for Apple abandoning iWeb, but they could have updated it just like EverWeb?
