So people can tell their buddies that they hit the club with 7 stamped on the bottom when they really hit a 1987 five iron.

This is part of it but dbl is also correct as well; as COG has become lower and deeper (espeically in a GI iron) you need lower loft otherwise you'd launch the ball too high and spin it too much.

You know why the cg moved down? Because the avg. golfer who select the GI was not able to launch the ball
Don't think that that same golfer would "launch it to high and spin it too much" when the loft would have stayed "normal"birly-shirly

Doesn't the same shift in CoG that launches the ball higher also REDUCE backspin?

Then you work on technique until you can mash it with a muscleback.

Till now never saw a serious swing speed golfer that needed a GI or even a super GI....
Hi. My name's Will. Nice to meet you.Not sure how serious my speed is now, but judging by a lot of the shots I hit this summer, it's higher than the designers had in mind, and higher than it was in February when I got fit for driver. But there's no way that I have any business playing "players" clubs, even though they are largely the clubs designed to flatten the flight and keep the spin manageable, something I had a big problem with this summer. And the lofts on my clubs are pretty strong (45 or 46 deg pw). I'd love to see a head designed to create a "players" flight, with GI or SGI forgiveness.

Okay... let's break it down. In your opinion, what are the attributes that make an iron head a GI or SGI head?

-Significant weight positioned around the perimeter and especially low in the head.
-larger head size
-significant offset
-sole design that helps prevent excessive digging
-lighter weight
-thicker topline
This is the kind of thing I think of when I think of GI/SGI.

Good list, I'd also add...
Lower and deeper CoGs
Stronger lofts
Usually designed for light weight steel or graphite shafts
These characteristics make me think that distance is the driving "corrective" force behind these designs. Either by weight, by length, by loft, by CoG manipulation, by sole manipulation, or by MOI these designs help neutralize some of the effects of slower swing speeds that would be more pronounced in "less forgiving" designs. Swing issues within the confines of a given swing speed are still going to be present no matter what, but they can somewhat be "helped" by certain design features. There are trade-offs between a club built to accentuate your best shot and one built to help ease the pain of your worse shot. As a general guideline, I think there are more benefits from a club designed around your particular swing speed. Then within that design there are options out there to "help" with the other issues.

Are there any notable guys on tour using GI irons?

So basically, a high speed, high spin, high trajectory, high handicap guy needs to get the most forgiving player's club he can get to have a club designed for his speed, then hit the range so he doesn't suck so much at finding the sweet spot?

Generally speaking, I think he would see more of the benefits from his much coveted skill if he did so.
