Grok (grohk): to understand profoundly. First coined by Robert A Heinlein in Stranger in a Strange Land. Now the foundation for a new type of search engine, which doesn't particularly interest this site (especially since we don't seem to be ranked all that highly in it) but also for a new type of puzzle, which does interest us.

You Grok? features only one puzzle, which appears to be updated every weekday. It's simple: you are given seven search terms that all relate in some way to an eight term, which is up to you to figure out. Once you have, you can use that term along with six others to find the final term. The puzzles range from ridiculously easy (Thames, fog, and Jack the Ripper all relate to, duh, London) to ridiculously hard (oil production, sustainable development plans and Mazanderan all relate to the Caspian Sea?).

It's a visually appealing puzzle, although there are occasional bugs. However, this is a fairly new site, and it will be interesting to see how it develops.
