Tangent is the 'hack' -- please do not ask me to define 'hack' -- I worked on for the Yahoo! Hack-U competition. The basic idea behind tangent is to basically allow you to fly off on tangents while reading stuff on the web -- from any browser which supports javascript.

Why a bookmarklet?

By aiming at all browsers and minimal installation -- both because I use a dual boot system and understand the pain of installing something on different browsers on different OSs, I was limited to using a Javascript Bookmarklet. There are a lot of great bookmarklets available on the net -- developers/designers shouldn't miss out on Design -- and with the powerful libraries available out there, making a bookmarklet which adds content to the page, alongwith nodes is not a problem at all.

Why the basic idea?

The inspiration for Tangent came from the way I read Trivia while surfing the net; reading up about something interesting and marking up stuff I want to read later by opening that in new tabs. Tangent just makes that easier for me to do.

Using Tangent

Get the bookmarklet here: http://kunal-b.in/Tangent . Select some text in any page, click the bookmarklet, and the rest should be pretty obvious. I'll put up a screencast as soon as I understand how to in Ubuntu.
