I have given you my input, which you continue to refuse, so I'm still left wondering why? I'm a professional marketing person, I basically make a living from giving such advice, advice I've given you for free here, and you yourself have admitted that you don't know much about marketing, so I'm just stunned as how you can totally ignore my advice, even trying to attack me for giving you this advice and then wondering why you don't even consider implementing it?
Actually, I'm not that much surprised. I've seen this a couple of times with technology companies. They think they know what their customers want, then built it (that's the management perception/customer expectation gap I mentioned above, really typical for technology companies). If their customers don't buy it, they think it's either because of price (they don't value it enough/costs are too high), customers don't know about it (they then think it's marketings job to tell them), or they need to improve upon their product but are limited by their own abilities to do so, so they focus on that rather than on what the customer actually wants/needs - see that, it's a downward spiral, investing or better wasting money/time into something that makes no difference to the customer only to be left wondering "why" again.
Once again, I can't tell you what your current and potential customers want/need - you've got to ask them - that's marketing.
Please, by all means, if you want to make this successful, hire somebody that actually knows marketing and give them the power to change something - I know you're reluctant with both things. However, if you want to continue as you've done so far, by all means do it and I put you on my ignore list and unsubscribe from this thread.
