For a while blogger/blogspot was making me fill in a CATCHA to make sure I was human to post to my own blog. I believe the reason was because many of my posts were a few short sentences with typically one link. Something like, "I need to look into technology blah, because it could help out blah blah." I didn't really understand this until I went to use Microsoft's Live Writer product and post to blogspot. It failed with an error message that directed me to a request a human review my blog. That all occurred and now I can post from from Live Writer. In fact, this post is using Live Writer.
