A flooded font has refrigerant (glycerol I think normally) continuously circulated through it to keep the beer lines cold. A non-flooded font doesn't. You can generally tell a flooded font in a pub because it forms ice from condensation.
As a homebrewer, you probably don't need one, and they're relatively expensive because you need a pump to circulate the refrigerant.
w00t!
