Menulicious is a utility like Delibar that allows you to access your del.icio.us bookmarks right from your menubar. One nice option of Menulicious is that it can display a bookmark count for each of your tags. An annoying quirk, however, is that your tags are listed under a "Tags >" menu; not directly under the utility itself.
Regardless, Menulicious is a Universal Binary, so it'll run a little faster on your Intel Mac. Menulicious is free and available either from Versiontracker or Kainjow's iPod-like website - surf to Software > Freebies > Menulicious.
