It also prevents all kinds of clients who (for various reasons) can't implement SSL from visiting your website. I'm sure this is a "small web" blog, whose author wants to be visited by e.g. a Commodore 64, an OS 9 iMac, or somebody who just wants to telnet in. If the sensitivity of the information on this page was critical or you were going to be submitting information then by all means yes, SSL is important, but if you're going to be reading a personal blog about calendars then http is probably fine. Of course the ideal solution is offering both and letting the client choose.
