I wrote a big reply to this ages ago but I had a network issue and it got lost
But yes! iWeb was the first web making platform I used back on my very first (not handmedown) laptop! After my parents split up I was traveling back and forth between them every week and I kept hogging their computers when I was around; so they got me a white Macbook 13 2007 model; it came with iLife 06
That summer we went on holiday; there were supposed to be some other kids coming, but things didn't work out and I was the only non-adult there for the whole 2 weeks, also there was totally no internet, so all I had were the pre-installed applications on my laptop, a camera and a whole lot of time!
As a "protest" I pretended that I was like Tom Hanks in castaway with his football friend, but instead of a football I found a melon in the shopping basket and used that! (Can you tell where this is going?) I took the melon all around that summer and photographed it, and when I found iWeb on my laptop I was super excited and decided to make a website for the melon. It was called Project Melon, and also there was a mysterious club called Club Melon you could join if you knew the password, there was also a blog I made for it called Melon Times. I actually had an .Mac/MobileMe subscription so I was able to put my sites online using that, although I don't think anything of them remains now.
The melon name stuck around though, and when I found neocities about 10 years later it was very much reprised
All that is to say; iWeb in some small way saved that summer and left some lasting memories! I recall it being a bit clunky, and the sites never really gave me as much freedom as I knew I wanted even back then long before I knew HTML; but having a simple way to just make a site and get it out there was so cool. Id like to play around with it again and Id love to see more people using it for neocities sites.
