Aye, I guess that in some cases your PS experiences might not help you get a job. But if you are a good Role-Player like many who posted in this thread are, you can always aim at "Did a lot of improvised creative writing".
I think it depends on how you bring it and how you can explain what you mean. I mean.. shouting "SHUT UP ALL OF YOU!" on IRC could be worded as "Adviced large community on general behaviour." And when you are a Sangwa or a Phinehas can't you just walk in and say "Give me the job, I used to run a Dark Empire"?
