I do not believe there is any competition.
Being a high poster is not easy. It might seem as if it would be, but it is not. When I first joined I took one complete day, read and responded to each unread topic as I came to it. By the end of the day I was worn out. I couldn't keep up, the new post were coming in so fast! I look forward to seeing Amma's response on a topic. She is one of the veteran's I look up to. She is always nice and pleasant and I enjoy the information she gives. I update a topic when I want to. Not necessarily when I have something to say because sometimes I will be busy and not update a post eventhough I had some thoughts on it. Some days I am more social. Some posts I have one word responses to. Other days I just want to read. We all have our different ways and they are all good ways.
Good post on your part. No, not competition.
