Besides a useful search function, another thing that I've sometimes wished I had for this blog is a simple way for readers to be notified of new posts. Now that I've given in and set up Google search, the first point is taken care of, and I may have found a solution for the second in a service called follow.it (their capitalization). The form below is supposed to allow you to enter an email address, click "Subscribe," and thereafter get an email for new posts. I think it works but I would be interested in having others try it and let me know if it works and if there are any contra-indications. One thing I'm not sure about, for instance, is whether it requires you to register with follow.it. I was already registered when I tested it. If it's useful, I'll tailor the colors etc. of the form so that it fits the rest of the blog and put it on the sidebar.
One possible negative is that it seems to send an email for new comments as well, which could easily be annoying. That may be something I can restrict on this end, I don't know yet.
