Hmmm I am worried that those who are already afraid of posting "too much" and are insecure might read this thread the wrong way (((hugs))) I see it as a site eval, personally.
I don't fit the category of a postaholic, with regards to the reasons why I post or lack the compulsions you list... but do fit it if you simply go by the count. But, being it's a fun thread... who cares!?
