Hi Zanny!

Huge fan and long-time subscriber of TE. One of my favorite election features you guys did was the Presidential Debate live-blogging but I believe this was recently replaced by what is basically a feed of Twitter accounts posting about the debate rather than TE writers. Do you have any plans to bring back the old format where your columnists weigh-in in real time for the upcoming 2016 presidential election?

Here's a diagram that shows the basic layout of a fracing well. The biggest difference is that it's horizontal rather than vertical. Basically, fractures are induced by pumping fluid (water) into wells at pressures greater than the yield strength of the rocks, and then kept open by a "proppant," usually sand.
