One of the things that I have seen over and over again in sl is the idea that people should not be paid here what "real" people are aid. for soemthings I can see this. For example sex. This si because sl ssex isn't the same as the real thing. But then graphic design and programming here are. It's not any different than writing a web server as far as I can see.
This is a good example of what I am talking about.
If the people who are doing it expect real world money, or are getting paid rl paychecks when they pay you for it, then they should be paying rl rates.
