My two cents is to complain about the five dollar price tag. Don't sell me five dollar software for a free social bookmarking service. I value my bookmarks and my data, but don't try to sell it back to me over, and over.
@bgkarma Despite the impression you might get from the name, this isn't an official Delicious application from Yahoo! I'm kind of surprised that Apple/Yahoo! allowed the name to be honest. I named my delicious app Yummy to avoid any trademark clash.
