Coolness for me - or for this little vanity site - or whatever. I got to use it as a demonstration for design concepts here at Xbox. Well not the whole site, mostly just the posting page. I don't use it often, but I have a DIV that is flagged as content-editable and a tiny bit of javascript that hauls the innerHTML from the div into the textarea submission box.... hey, wake up.
Anyway, the people here who are.... less than technically proficient love the idea that they can just type like they do in word, hit control-b for bold, type links and have them turn into links, etc and then "magically" transform what they just typed into HTML to post on their sites (this is rather than using MS Words hideous html exportation feature). So to show it in action I pointed them here.
Yay for me
