In my experience there seem to be four types of people: those who don't have a lawn; those who have never heard of clover on lawns; those with clover on their lawns; and those who live under the unrelenting glare and iron thumb of a homeowner's association.

Clovers are great, they give bees something to land on in the barren wasteland of lawns that is my neighborhood. I also usually let whatever random plants/weeds that pop up grow in the peripherals. If they can manage to thrive in my nonexistent gardening then they deserve to be there.
