What's in a blog? Facts? Or Insights?

I recently viewed the blog of a colleague who was detailing a vacation he took. Much of the content was around the facts of the journey - the cab picked me up, the plane was late, etc.

I get more out of blogs that reveal insight rather than sequences of events. We bloggers should seek to convey insights rather than facts... and relegate the details to a journal or something private (still not sure what value such a collection of facts would provide).

I promise to seek to avoid regurgitating facts in favor of sharing insight here.
