Or, Why I Changed My Posting Policy.
I've gotten a couple comments recently on my blog recently urging me to check out some biotech stock or purchase a summer home in Hawaii or some such rot. This was pretty clearly an attempt by certain entities (I will reserve "unscrupulous" for later, although the stock posting smelled suspiciously like a pump-and-dump) to game their page rank.
And, since my blog is read mostly by people who know me personally, and are quite capable of sending me email directly to let their feelings be known, I decided I wasn't missing much when I restricted posting to registered Blogger members.
So, if you really have a burning desire to respond to one of my diatribes, you'll just have to sign in.
