Commenting on your own posts.

One of my first observations when I discovered the power of blogging
was google seems to handle blog posts like normal pages. I saw post
coming up high on google searches. But I noticed blog post are
driven by links and comments like other pages. Links are another
subject... which I am not asking about... but about comments I
noticed... the more people that comment the more it seems to keep the
post alive in the google ranking. I have seen posts that have
horrible content yet rank well because people comment a lot on
these. I do not comment on my own blogs under false names and make
fake comments (nor do I intent to) but I think some big bloggers do.
Are my observations correct that comments alone can make blog post
rise and the lack of comments make posts fall?

Thanks,


Mark
