Do you think the level of academic qualifications and life experience that a member of forum has, has a direct influence on the quality of post that he/she makes here on this forum?
Do you feel users who are known to be quality posters in various boards are individuals with high educational qualifications and vast experience.
Not really, or it has little effect on the quality of posts.
What's affecting the posts I think is the experience, and the knowledge of the user towards a particular topic.
TBH, I'm not that fluent in English when I started interacting into the forum, but as I watch English documentaries, English videos on Youtube, and speaking with English people sometimes, my way of speaking English got better, and better though I think there might be some times where I have broken English when I'm speaking with other people, and when I'm posting here, I can say that it's better now. I'm not a native English speaker as well, so I might have some broken English as well.

Academic qualifications? I don't think so because there are some who didn't finish their school, and yet they're very good in interacting with other people.
