Yes it works, especially on weaker weeds (dandelions require multiple doses). However, because of the high acidity of vinegar, it's very bad for your soil. You only want to use this technique on pathways or areas with bark/wood chips.

A better and more soil-healthy technique is to collect leftover (and often free) burlap bags from your local coffee shop, place those on the ground, and cover them up with dirt or wood chips. After four or five years, the burlap will destroy any of the especially noxious weed roots (i.e. dandelions) and deteriorate back into the soil. Of course, you'll still have to do light surface weeding above the burlap.

Finally, I also agree that I wouldn't want to eradicate clover. It's a nitrogen-fixing plant and actually replenishes nutrients in your soil, unlike grass and other common weeds.
