There are somethings that you have to be a major nerd to appreciate. One of them is my new favorite toy, Goosh. Goosh is a new web app that allows you access many of Google's features (search, maps, images, etc.) through a UNIX-like command line interface. If you're the type of person who would rather "shell in" than open up a GUI, you will appreciate this speedy web app. If the previous sentence appears to have been written in some strange hybird of English and technobabble - a) it was, and b) you might not appreciate this app that much.
Does Goosh offer any major advanatage over just navigating to the Google web pages and searching the traditional way? Probably not - other than the automatic geek-cred you will pick up by using it. It is pretty quick, though, and I would be interested to see how it runs on my Treo. It's written in AJAX, so I'm not sure how much the Blazer web browser will like it.
Anyway, it's quick to load and fun to play with, so I recommend giving it a shot.
