OpenDNS Shortcuts - a command hotkey type service, even has a widget so blog visitors can grab a shortcut link for the next time they visit your blog, see other hotkey/shortcut services.
deskload - a simple webtop (see desktoptwo) where you can store bookmarks via the File menu and access them the same way or on the actual desktop
LiveChat2im - a blog chat widget for your blog, where the blog owner can chat back using an IM client, and you can add multiple IM accounts (team based), also see Plugoo and meebome.
Tagseasy - bookmark with a toolbar and share them in a network, ideal for business…seems similar to the closed network idea of Yoono, although I think they have changed their business model of late.
TagandFile - upload your files to a server and tag them and attach notes, holds a version history, give share access…in a similar file hosting space as Box. [via KSU]
