Points for trying?

So, one of the things I said I would do every day is post in this blog. But I don’t have anything to really say today, and I also want to go to sleep. So I’m wondering whether putting up a contentless post is good, because it trains me to post no matter what (which results in more posts and hence a better blog, over time), or bad, because it drags down the overall quality of the blog. My temptation is to say that there are two opposing effects here, and which one predominates will depend on a number of factors, which I could, but don’t wish to, enumerate here.
