I love having clover in my lawn ! I like walking barefoot in clover,too, and it is much softer than grass. Plus, it makes a great soil enricher when it is mowed. Speaking of mowing, that is about the only downside that i can see to the clover lawn. It grows very thick and heavy, so you have to keep it well-mowed, or it will be hard to mow if it gets too tall and thick. Other than that, I can't think of any problems with it, and it does spread easily, too.
It blooms all summer, so if it is not kept mowed, you will have the little white or purple blossoms all over your lawn; which is either good or bad, depending on how you feel about flowers all over in the lawn.
