Talking to someone at Apple, they told me that the reason iWeb wasn't kept up was because of the advent of Facebook around the same time. Makes sense, but I am not on Facebook and prefer iWeb. Great to know it works with Mavericks.
Before I learned iWeb, I learned Freeway Express. It is NOT as easy but it is similar and has an inspector palate like iWeb.

Here is one of the basic videos:

It does allow you to insert a link to further down a page, lets you preview inside a browser before you upload it, and I use Fetch as my FTP and host it on GoDaddy for about $60 a year. If you pick the Deluxe package, you can host as many websites as you want for the same price. It does not have the premade templates that iWeb has. But the html is searchable, unlike iWeb which sometimes turns a text block into an image.
There is a 'pro' version but the 'Express' works fine for me. It's $49 and they have a very active forum if you have questions: http://www.freewaytalk.net/forum/view/5. You can try it out for free with a 30 day trial.
