what to blog about a blogger

What sort of person do you think I am, from reading my blog?

There seem to be so many layers and facets about knowing a person - There is knowing him in a social setting, there is knowing him on a 1:1 basis, there is him showing you the whole of him according to his reality, there are his fantasies and dreams and it's up to you whether you will help him achieve or turn your back on in disdain.

There are also his blogs.

Someone that I had considered to be a thoughtful and free-spirited person I later realized to be narrow-minded and judgemental. If it were for the blogs I wouldn't have known...

I'm not sure what point of reference I should use when I interact with this person in the future - from our past conversations or from the blog?
