After having changed over to Safari a few months ago, I noticed the lack of a fast plug-in for my Delicious bookmarks. The delicious.com website is okay, but when you use it a lot, its lack of speed can be annoying.
Hence I decided to write my own super fast Delicious 'plug-in' which isn't actually a plug-in at all. Instead, it's entirely browser-based; you can try it out at this URL. The site makes use of a new feature of HTML5 which allows you to have local storage of remote data. This makes the site very fast, but currently Safari 4 Beta is the only browser that supports this feature.
[robg adds: I haven't tested this one, as I don't have any public Delicious bookmarks, which is what the site works with. As a result, you don't need to enter your Delicious password to use the site -- so you can test it without fear of password harvesting.]
