Do we have any facebook application authors/creators in here?

like the title says. do we have anyone here who has made few facebook apps and had success with them? im starting to get into fbook for a lil bit lol and made 2 apps so far. one using a frea creator which i did for a laugh. and its only a week old yet has over 300 users but only like 20 fans.

now ive heard u can monetise apps if done right with the fan based and what not.. so does anyone have the experience in this field here? would be intresting to see if we do have any creators on board..
