I recommend slightly flirting, it seems the people I borderline flirt with always come back for more. As ever, indulging others with complimentary behaviour gets the same in return and generates their interest. Writing 'me specific' posts, blogs and threads doesn't tend to generate a significant response other than some head nods.
It isn't necessarily what we might be inclined to do naturally as introverts, but hey, I'm a Te person and I have a flexible Pi soul. *ponders*
