I've played the Dutch Stonewall quite a bit in the past. It was generally against weak (but equally skilled opponents), so it all went fine. The idea is to get a kingside attack while holding the center solidly, at least most of the time.
The issues with it is as Do It Right explains. There's also the plan to exchange DSBs (white initiating this, assuming we are talking about this structure from the black side) with b2-b3 and Bc1-a3. Black would have to counter with ...Bd6 and ...Qe7, else he would end up with ECO A94:

As white, you have a bit more leeway with such things, but again, Do it Right explains how it's inflexible. I've played such structures many times myself as I used to play the Bird (1. f4). There tends not to be any great, quick attack, even though the idea is to aggressively push forward on the kingside. And the other side has some pretty simple positional ideas to work with (mainly the big hole left on the e-file).
Still, I know I will end up playing this pawn structure from both sides of the board in the future. It's not totally without merit. The center really will be somewhat strongly locked. The advanced f-pawn will help you advance with pieces on the kingside. Against the right opponent, or occasionally just to mixt things up, it should be fine.
