Writing connected posts is interesting change. I usually write just some random things that happen to come to my mind at that moment. But occasionally I have had some repeating topics I have stayed for a while like the banana episode for example.
Then there has been a few topics so big and deep that just one post couldn't have fit all of it or wouldn't have made it clear enough. A good example of this was the recent Graham's number post I made that required a series of preliminary posts to explain enough of the background for it to make any sense.
