Amazing Site Gets You Up To Speed On Any Subject [1]
You need to find out everything about Nigeria. Or glass. Or woodpeckers. Or Einstein. Or pianos. And you need to do it relatively quickly. Maybe because your boss asked you, or perhaps your school teacher. Either way, you'd probably start by Googling it, wouldn't you?
If so, here's a different method, and one which might actually be better too.
Head to www.instagrok.com [3] and type in the word or phrase you need to know about. In a couple of seconds, up comes a mindmap-style diagram with the keywords you need, and the right-hand panel shows links to relevant web pages. Click on one of the mindmap nodes and things get even more detailed.
In the screen shot below, I've started by searching for information about CPUs, and then clicked on the Chips node in the first diagram.
Try it, and grok something new today.
