On blog titles starting with "On"

I like them.

I also like chapter titles in books that go something like:

"Ch. 6 - In which Arnold encounters a bear."

I don't think I can articulate why, I don't even know if I know why, I just know that I like them. Maybe it's because the author is him/her-self giving you a the subject. It comes across in a way that is different from other titles, as they are dry and impersonal e.g. - "Ch. 6 - The Bear" - Oh, a bear? Why do I care about a bear? I'd almost rather have the sparse "Ch. 6". Don't bother telling me about the bear, I'll get to it, and I'll get why it matters when I do. But if the author says "In which Arnold encounters a bear", it's though they're saying "Psst, Hey... Arnold totally runs into a bear in this part and it's awesome, so read fast but pay attention." Now I'm totally stoked about the next chapter.

It's the kind of thing that causes late nights reading. I'll be a few pages from the end of chapter five, eyes blurring and drifting across lines, creating words that weren't there and mentally distorting what I've read. How much further? I wonder. I slide a finger in the page and flip... 1... 2... 3... 4... more pages to chapter six. I'll stop there. Ch. 6 - In which Arnold encounters a bear... Protagonist meets bear? Really? Is there foreshadowing in Ch. 5? Am I missing something right now? Will there be a cliffhanger at the end of Ch. 5? I have to know about the bear! I wipe my eyes, maybe get up and go to the bathroom, get a glass of water. I am awake now, awake with intent. I must finish this chapter and read the next. Minimum. I wonder what Ch. 7 is called? Will there be a cliffhanger? What happens with the bear? Is this how the Antagonist comes into the story?

Two hours later, I will know. I'll also have read at least four more chapters, all with the same anticipation. I will be very tired, but it will have been good, and definitely worth it.
