I would certainly use favetop for aggregating videos and music. This feature is just awesome. I agree with others - bookmarks are best for launching links and webapps, specially when you are using ONE computer and only ONE browser.
Well, a question to site owners: do you track my clicks on links?? ;)
It looks like a competitor. Pik has a UI that's in the browser window rather than a pop-up prompt, which allows you to search for commands. Pik also shows you what commands are popular on a given site/page, which makes it easier to discover commands.
