Why reward laziness and sloppy thinking? Anyone interested in HFT can peruse a few dozen threads on HN, where these questions have already been answered at length.

Because if you really are annoyed about it perhaps you should explain why it's wrong so it will eventually stop being proposed. People are wrong about all sorts of things, that doesn't mean we need to belittle them or be snarky.

Regarding the snark:

The OP suggests making major alterations to the functioning of equity markets, without any evidence that he's done any research or even thought carefully about the costs and benefits involved. He suggests that the proposed changes are highly beneficial (we might even cure cancer!). How seriously are we supposed to take this sort of thing? Should we also welcome the kind of amateur mathematician who has a simple proof of Fermat's Last Theorem?

Personally, I think a bit of snark is warranted.
