What's the average response rate?

Hi,

Does anyone know the average response rate to messages sent to women on this website?  One of the American dating websites published some statistics and their average response rate was an unbelievable 36%!  My response rate is below 6% and I'm not sending messages blindly, but only to carefully selected interesting girls with whom I think I might find a common language.  Is it something wrong with me or do all men have similarly low response rates?
