Danny blogged a great overview of YubNub, a service that “gives you a command line interface for search” a couple of weeks ago.
Two quick updates. First, you can now use YubNub to search all of Search Engine Watch (via Google).
The command is sew [foo].
You can also use the command sewb [foo] to search only the SEW Blog.
Second, a post on the YubNub blog points out that YubNub now has an interface optimized for mobile web users.
