x = 1/a
where x is the # of months you must wait before posting again as to properly celebrate your blog's anniversary, and a is the current anniversary (a = 1, 2, 3, 4, ..., end of the Internet).
I bet you thought the relationship was directly proportional, eh? Well you were wrong. It's inversely proportional.
With a basic understanding of mathematical limits you would notice that as a goes to "end of Internet," x goes to zero. Logically this would mean you would have to post two posts simultaneously, the anniversary post and the following post. Without getting into relativity, spacetime planes, or hyperbolic-orthogonal points, let's just say this would be hard. So don't let your blog last this long. Seriously, only a really arrogant person would honestly think their blog was significant enough to last all the way to the end of the Internet. Don't be that person.
So anyway...see you in September or maybe the end of August.
