We found very similar results. In our experience (Zaarly) tech press has yielded very little long-term value, especially from a user growth perspective. The retention rate of users from article traffic is very, very low. An article on TC, VentureBeat, Pando, etc yielded us very little beyond your standard insular chatter amongst the tech community.
On the other hand, I think tech press can be useful if the goal is not solely user acquisition. For example, if you're simply trying to raise awareness of your brand and product within the tech community, especially amongst investors, I think tech press has some value. Other than that, YMMV.
