At the top of this page, you’ll see a “next blog” button, and clicking it takes you to a random blog. In an idle moment, I clicked yesterday, and on the third click, was presented with a blog I didn’t know, but which was written by someone I do know, and featured pictures of many people I know. Since, according to this, there are currently 133,000,000 blogs – and OK, Blogger is only one platform, but probably the biggest – what are the chances of this happening? And should I buy a lottery ticket this week?
