I bitched about this almost two years ago, and it's finally fixed with the new del.icio.us redesign, which, I must say, I really like a lot. You can now sort your del.icio.us bookmarks, either alphabetically, or by "Most Recent," by which they mean "most recently added," I believe.
Oh, and I guess it's just "delicious.com" now. They went and killed the dots.
Anyway. Thanks delicious! And nice work!
