My experience reflects this strongly! Ironically I performed what you describe as extroverted networking relentlessly by nature with great success for years, went to engineering school as an adult and dutifully attempted to perform 'networking' as it was recommended to me and as a result had almost that exact 'introvert networking' experience. Like, your description caused me to recoil in horror from remembered embarrassment. Because of that I think the 'introvert networking' experience is simply following the procedure as described.
