Easier YubNub installation in Safari
Noah Mittman has come up with an easier way to add YubNub to the Safari search bar: "just wanted to let you know there is a freeware Safari add-on called AcidSearch that works very well with the site. It allows users to configure their own searches into the field normally locked to Google. A nice touch is that there is a panel built-in that lets users select and contribute search strings, so I've added YubNub to the list. So if you wanted, you could tell people to install AcidSearch and choose YubNub from the "More Channels..." list as way to install YubNub into Safari."
