Whatever the case, as a whole it is still too high.
How do you know all "apostates" post on the net and read your posts? I didn't read your thread asking about employment. I work two jobs. See, here is one person you didn't count. Maybe the more accurate thing to say is that message boards in general tend to attract people who are disabled, or unemployed, or lonely, or bored, or unhappily married, or single and lonely, or students or people have too much free time on thier hands, etc. etc and so on and so on? Then there are people who work but post on boards for a hobby or to find support or to give support.
There are people who are "apostates" who don't even own computers much less post on the net. There are likely many who are members here who are too busy to post very often. This is just amusing, your little employment study.
