I used to use MS Frontpage when I was a PC and since converting to Mac, I didn't want to invest into Dreamweaver or learn anything that would eat up alot of my time. So I did some research and iWeb seemed like the best option for me. For what I use if for, it fits me needs, it's quick, easy and simple.
If you need any more info, give me a PM. Hope this helps.
I use iWeb for my two sites. I love it; simple to use, but makes really nice websites. Check 'em out: www.pantherphotosonline.com and www.rubyvalleybaptist.com
