Actually, I am. There comes a point (about 150) when the serious threat represented by a minority attack becomes a realistic game plan. And at master level, there is a school of thought that suggests the best way to win with the Queen's Gambit Declined as White is to play the minority attack in the Exchange Variation. I can remember several Swiss tournaments where Keith Arkell ground out a couple of his valuable wins using this line, without apparent effort. The other classic setting for the minority attack is the Sicilian Defence, and Pal Benko has been a great exponent of this winning method in the eyes of John Watson.
This session is an example of the need to study middle-games and not just openings. First of all, what is a minority attack?
This is the classic setting for a minority attack. White has two Pawn islands, the larger of which is on the King's-side and you might think that White's best plan is to advance it. However, as well as exposing the White King castled King's-side, the advance would be in the teeth of Black's opposition on the e-file, and an advance of the f-Pawn would leave the e-Pawn effectively backward.
Instead, White uses a similar logic to argue that it is best to use White's own half-open file, the c-file, as the basis for an attack on the Queen's-side. White plans to advance the b-Pawn and either play b5xc6 (b7xc6), when we have a Black Pawn on c6 which is backward on an open file, or ...c6xb5, when the d-Pawn will become weak.
The advantages of a minority attack are several:
- It emerges directly from the Pawn structure
- It does not depend on the presence of Queens, and the attack can be pursued right into the endgame.
- It can work like clockwork, yielding points 'just' on technique.
This is the Sicilian setting for a minority attack. White in fact has an uncompromised Queen's-side majority, and you might expect then a general Queen's-side advance. But typically pressure on the e-Pawn leads White to play Nb1-c3, in front of the c-Pawn, and Black usually nails it down with pressure on the half-open c-file.
So, encouraged by Black's lack of space and lagging development, White can punt down the King's-side, while Black can play ...b7-b5, engaging in a minority attack against the White Queen's-side Pawns.
Of course, the Sicilian is one of the most complex and flexible openings, and not all games can be interpreted in this way; nonetheless, this reading of the Pawns explains a lot of what goes on under the bonnet of Sicilian systems.
Now, I'm just having a look at playing and recommending the Orthodox Defence to the Queen's Gambit, so this the minority attack an important thing to see coming, and know how to defend against it. Let's look at the positive side of the Minority Attack first, before trying to work out what to do about it.

Defending against a minority attack.
Now, what can you do about it? Actually, lots. Temperamentally, we might find the most appealing response in the middle-game is to deliver a mating attack on the other side. Realistically, it is helpful to combine this with other defensive methods, and to be aware of ways of counter-attacking on the Queen's-side. We shall review:

"The minority attack proper has come to an end with White having inflicted a serious weakness on c6 and in fact controlling the entire left flank. It looks like a fairly simple matter systematically to attack c6 and, if not win it, then at least drive Black's pieces onto horribly passive squares. But the sequel demonstrates that matters are not to simple: Black's Rook on the third rank not only defends c6 but also creates pressure against White's King's-side" - Nigel DAVIES

From the point of view of the opening variations that Polu was looking at, perhaps it doesn't, but from the point of view of a player handling the middle-game, it can form the basis of totally separate plans.

The irony is, that with all these nifty defensive ideas being better understood, the Exchange Variation is now played in a much more flexible and dynamic way with White very often going for the advance e3-e4!

What to do about that approach, I can't do in much detail here, but the following game may repay study. Informator has some excellent notes.

Plan B. 11...Be6 12.Rad1 Rc8 13.e4 dxe4 14.fxe4 Ng4 Black relies on piece activity to keep White's Pawns under control;
the game takes on a hypermodern air. 15.Bf4 Ng6 16.e5 Bg5 17.Bxg6 hxg6 18.Qd2 Bxf4 19.Nxf4 Bc4 20.Rfe1 c5
A classic flank blow against the centre, but Black has to steer through some stormy tactics. 21.Ne4 cxd4 22.Nd6 d3 23.Nh3 Rxe5 24.Nxc8 Qxc8 25.Rxe5 Nxe5 26.Qe3 f6
Black has much compensation for the exchange in the advanced Pawn and strong Knight.
