Hi bremmer,
I too have created a system which I believe is far better than anything else out there, however I do not have the resources to market the product. My choice was to offer the product for free. Yes I know this seems like madness but here is my reasoning:
As it's free, more and more people are downloading and using the product.
This 'snow-ball' effect gives my site more links to, thereby improving its search engine listing.
I am currently developing the next version which may have a small charge associated with it
Or someone from a big software company might want to buy you out!
