So Banshee, your experience is based on what exactly?
by your own admission, never sold anything.
I've been in this business over 25 years during which time I have writen corporate, commercial, shareware and freeware projects, but these days I tend to stick to simple freeware projects only and earn my money elsewhere - this is all I eluded too above. I like to think my experience has a value too, but apparently not.
Frankly i'm not much interested in a slagging match with a walking ego (I could list my credentials too - I just dont feel the need).
My advise to Vorderman is if he gets under 1-2% conversion ratio from demo/sales then he should review the project and keep working at it, because there's no reason why he shouldn't get a sale from every 50-100 demo downloaders. If you or anyone else takes offense to that then fair enough, just dont go asking for an apology.
