The first time I saw the yubnub website I was thinking that no one would need this website at all but after some testing it became clear that it offers an easy way to access many services very fast without depending on bookmarks or links. If you do work with the command line in Windows or Linux you feel right at home, you enter a command and some parameters and yubnub does the rest.
A list of commands is accessible by entering ls into the form field. I think an example will illustrate the strength of yubnub; wp ghacks searches wikipedia for the term ghacks, gim ghacks searches google images for ghacks. y or g searches yahoo or google for a selected search term. That is not all of course. AM title searches amazon for the title that you enter, random 1000 returns a random number between 1 and 1000.
A good selection of commands that should be useful for most users are Jeremy’s Picks which displays a list of about 100 commands. It is possible to create your own commands. You do select a command string that is not used yet and select a url that uses variables to perform searches or operations. One example would be http://images.google.com/images?q=%s which is simply the search string for google images.
The search string that is entered is substituted with %s in this example. It is possible to create more advanced searches with more than one parameters.

Have you had a look at Favlog? It works sort of like YubNub but also allows you to personalize your keywords.
