An older friend gave me great advice one time from his experiences. You need a contract that sets expectations when doing any type of work, doubly so when it's for your friends. Of course if you're just answering questions here and there (like I'm doing here for you on HN), IMO that's what friends help friends do. But, when it comes to really doing work for someone, you have to be compensated. And like I said above, you have to be explicit about the compensation. Otherwise you learn the lesson the hard way like my friend did where he lost a bunch of friends b/c of a startup where assumptions were made and things went south.
