Sure, but why have a pretty date at the top and then make it incomplete? I don't want to scroll down to figure out if a blog post is recent, or look at the URL. This theme (or a variation) is used on many blogs, and not all of them use pretty URLs with a year in them.
My bank does this! The assumption is that when there is no year, it is the current year. They are trying to be smart with dates and I don't like it.
Funny thing is that when they developed this feature, they made a bug so if you scroll down to the year before, the years appear, but now dates from the current year are wrong as they appended the year before. That's what you get for trying to be a smartass.
