Why are organic solvents usually volatile?

Most of the organic solvents that I'm familiar with also happen to be very volatile. Is this a coincidence, or is there some underlying property of volatile compounds that make them good organic solvents?

Volatility is often a desirable property of a solvent. It makes it easy to remove the solvent (by distillation or just evaporation) when you want to. So we deliberately choose volatile chemicals for many applications.

In general, the more volatile chemicals in each category are more likely to be used as solvents -- acetone among the ketones, methanol and ethanol among the alcohols, pentane, hexane and heptane among the alkanes, and so on. But there's nothing intrinsically volatile about organic liquids. if you want a low-volatility solvent (and sometimes you do), you can find examples with a wide variety of chemical properties.
