5.0... what's with the numbers?

So it was pointed out to me that I should probably explain why the posts' titles start with a number. My friend identified that one of my speech patterns was to use the phrase, "So it's interesting..." (easily identifiable as the name of this blog). She started to ask, "how interesting; on a scale of 1 to 10". That way she could decide whether it was worth her time to listen or just pretend like she was listening. Now I say a number which represents how interesting I think the noteworthy piece of information is.
