First, this is a technical audience. Plenty (most?) of us couldn't give a shit about what marketing says. I believe about half of what comes out of the mouths of sales/marketing folks -- for good reason. We don't care what Gardner or some firm you paid to write up a report says.

Personally, I have a real dislike of sales/marketing folks and I will avoid them at all costs... so, no, I don't want to give you my name or e-mail address. I don't want your people calling me, interrupting real work. I don't want to view your webinar. I want to look at the technical details -- the facts -- and decide for myself and then, quite possibly, completely forget I ever heard about your company and go about my day.

Last, don't fool yourself. The downvotes aren't "validation" -- at all -- but, hey, go on living in your fantasy world. If it really was as awesome as you seem to think it is, it wouldn't be hard to market. To the contrary, the damn thing would sell itself and you wouldn't even need a marketing department.
