There are a ton of Notepad apps out there, but they are all clunky to use.
My goal is to make 3banana as easy to use as a Google search. I'm writing plugins so you can post notes from QuickSilver, shell, FireFox, or write your own using the Python API.
Here is my updated pitch:
3banana makes it easy to jot things down and makes your notes more useful, whether it is by helping you find something on the go or by allowing seamless collaboration with your friends.
Tap into your friends' ideas and expertise, and get instant feedback by sharing your notes on Facebook, Twitter, Email , AIM or wherever your social graph lives.
