The more comments from a user, the more accurate the system. In the case of HN, many people make less than 10 comments and the majority are shirt responses (i.e. contains minimal data).
If you try "postgresql" or something, there are enough people who have discussed it to provide good results. If you type "hnprofile", likely only these comments will show up.
