(Probably only Blogger bloggers will know what I'm talking about here, but so what, congratulations are in order.)
You know that "Your blog post published successfully!" page that you get after you click Publish Post? I just noticed that the obvious link on that page has changed from "View Blog" to "View Post." This means that for someone like me, who no matter how long he proofreads in Preview mode sees his typos only after clicking Publish and so has to once again start the cycle of Edit/Publish/View, you get to see your post measurably faster, since you're not loading your whole bloated (in my case, at least) main blog home page.
And! When you multiply this by the gazillions of Blogger blogs out there, the savings in server load (and hence, electricity) must be immense.
So, nice going, smart programmer, whoever you are.
