Well, yes I would love nothing better than to do something that involved writing or editing or reviewing literature, but... I have no "experience" and my degree is unrelated. That pretty much leaves me with only a chance to write, and someday, I will. That was always my dream as a child, and I have some books that I wrote in elementary school still to remind me of that.
Sedaris is hilarious - he is a lot like Seinfeld, in that he points out day-to-day happenings in life, that when you really stop to consider them are very funny. I have read Confederacy of Dunces, and I also did not find it as funny as many people thought. Just not my type of humor, really.
One final thing I was thinking about this morning, is that I wouldn't be afraid put a little more unpredictability into your book. I think of the best thrillers I have read, and in many of them, things happen that you wouldn't really have thought would occur - like in the Camel Club series, a main character dies. In the Dragon Tattoo series, all kinds of horrible stuff happens to the main characters. When you throw in some bad stuff that happens to main characters during the action sequences, I think it puts the reader more on edge, because all of a sudden it is like we can't really trust the author anymore. "Man, this character that we loved from the beginning just got gang raped by gorillas, who knows what the author is going to do at the end - no one is off limits". And, it makes the characters feel a bit more human, if bad things can happen to everyone. While reading, I felt a little that everything was going to turn out cheery in the end of your book - the guy would get the girl, solve the crime, the good guys would triumph and the bad would fall. Now this certainly can happen, but throwing in some more bumps along the way might keep the reader guessing more if it is actually going to turn out OK. This angle can certainly be overdone as well, like in Ludlum books where the protagonist gets shot like 50 times and just walks away, but I'm sure you get my point.
I remember in one of my HS English classes we were reading Poe, and my teacher wrote on the board "Fascination with Horror", and explained how people have a need to explore pain and suffering through reading so that we can fulfill some part of us that is almost evil in a way, our dark side. Maybe it makes us feel better about our own day-to-day mundane existence, but whatever it is, I definitely agree. I think in thrillers this fascination can be used to a huge advantage, especially when it involves the characters that we like the best.
Cheers
