Sounds like analysis paralysis. Read posts here, pay attention to what this audience expects, and then post your work. If you really want to find a source on this topic Michael Lynch (mtlynch) wrote a book called Hit the Front Page of Hacker News and you can find it if you search for it (I haven't actually read it), but I think spending an hour a week reading HN and asking yourself why a piece of writing did or didn't work for this audience would be more worthwhile.
