Completely agree with the "giant time-slurping vortex" part :-) In the mobile world the {product}app.com convention is pretty prevalent and has opened up some choices. You could always start a new convention for web-based products. I personally don't think a single product needs to have its own unique domain. Most browsers nowadays have the combo URL/search field feature (or the search field is right next to the URL). Someone typing in the product name will likely find it one way or another.
