I'm not a web guy by any stretch of the imagination, as you well know, but I find doing webdev really easy compared to any GUI library out there. If I can say "ok, this is only going to work in embedded Webkit/Chrome/whatever", I can whip up something that's pretty and functional in no time at all. When faced with the same task in GTK/Qt/Wx/whatever, I fail miserably. I've done a good bit of both, but I doubt I'll ever go back to making desktop apps -- I can always embed a webserver into whatever I'm building, and do the UI that way...
