Just had a play with yubnub…wow, this tool is very cool!
You can add a command to the system…command label, description, plus the URL.
Then you can go to the search bar, enter your command and it will take you straight to that website.
Good thing is that you can install the plug-in, so you can easily search from your browser.
So if you want to go to Wikipedia all you do is enter “wp” in the searchbar and your taken to the website.
The browsable list has the, command, website name and URL…but if you want to go to a website from the plug-in you will probably have to commit some commands to memory.
The immediate problem is multiple commands for the same URL…as an experiment I just made “wpedia” which takes you to the same URL as “wp”
…so there may be a bit of clutter
The unique thing is that a command will only go to one designated URL.
The reason I say this is, what if you don’t like the “wp” command for Wikipedia, well as just mentioned above make your own command for the same URL, but you may prefer this command to mean Wordpress…but too bad “wp” is already taken.
So this leads to…can yubnub be accessed via a log-in as a personalised version, this would be great as you have control over the commands.
According to my obervations your commands won’t be able to be automatically included into some sort of folksonomy (unless they are unique commands) as the same command label can’t be designated for more than one URL.
The only way to share commands is by entering them in manually into the yubnub home page.

The only similar application I’ve come across is ActiveWords.
