Titles for Blog Entries

I've seen many blog entries written about blogging, but never any about coming up blog entry titles, which is an art in itself.

I realized that I needed to put more psychic energy in that direction when I started naming my next entry, "On Spirituality". Just adding an "On" at the beginning of a title may be grabbing when first employed, but, at this point, I feel like I'm falling on it as crutch and have used it for nearly 10 entries (i.e., 'On Parents and Entrepreneurship', 'On Hearing Kaleil Isaza Tuzman Speak', 'On Listening to the Former Chairman of the SEC', etc.).

In the past, I've haven't put too much thought to coming up with a title. Today, I decided to read three articles that will hopefully help:
