I've moved the thread in question to GCC. When I first saw it, I debated as to whether it was a tutorial. Tutorials generally are to teach and educate others (which by definition it does educate). But the quandary I had was to how much of an opinion piece it was versus a simple educational fact.

If you think a tutorial is perhaps in the wrong location, then mention it to a moderator.

As for Gore's I was quite disappointed that his ended up the way it did. Granted not all the facts may have been accurate or lacked details it had merit somewhere.
