Thanks for the great feedback.
We don't contact people in your selection or connections. We want to focus on the small verticals where there is a high chance of match, like academicians, senior executives, developers, kernel developers etc. By spreading the word, you don't mention your selections. But if that still disturbs you, to be seen on jobrupt, you better not spread the word as privacy comes first.
Thanks for the great ideas on focus, niche, getting traction etc. They are great hints going forward.
