I spend a lot of time replying to people on Facebook. That time is spent on writing these detailed posts that get lost in the ether. If I post a reply that is longer than a sentence or two, I might as well start it as a post her eon my blog. Then you can have a single place to review and peruse my thinking on various subjects.
Yes, it might be messy, and yes, it might be disjointed. But with this, I can go back and edit posts, and perfect them as I either get more detail, or those brilliant afterthoughts that often come to me hours or days after my initial response. I might also start throwing some pix in here, like those I took around the tailgating for the Superbowl.
