So I've started working with the Dojo Toolkit -- mostly because I ran the demo for it, and I was impressed by what it could do out of the box. It does have a very nicely featured demonstration set.
I've mentioned this to some friends and colleagues, and instead of thoughts or experiences with this toolkit, I got back a whole bunch of comments about why I chose to work with Dojo and not "my favorite toolkit, x," where X is either a larger distribution that includes Dojo, or a smaller, more specialized distribution that I've never heard of. The other suggestion I keep hearing is "Prototype".
Anyway -- it's not that I don't want to hear about toolkits, but there is a certain undeniable power to a decent demonstration set -- not just a verbose description. And THAT is what got me to actually give Dojo a serious look.
Once I get what I'm trying to do fully functional, I'll be sure to post it here. So, far, I've only played around on my home computer.
