“Everyone has things they blog about. Everyone has things they don't blog about. Challenge me out of my comfort zone by telling me something I don't blog about, but you'd like to hear about, and I'll write a post about it. Repost in your own journal if you are so inclined.”One version I've seen adds: “Ask for anything: latest movie watched, last book read, political leanings, favo(u)rite type of underwear, graphic techniques, etc.”
Anyway, you get the idea. I will only add: “within reason.”
Go. If you must.
