You should figure out if we're lactose intolerant so you can write your comics accordingly. Sometimes they just have too much dairy.

Hmm, maybe the demographic data you want is: how much of our detailed demographic data do we believe has already been collected by our ISPs and browsers, and how much do we think your publishers would pay for it?

I recently filled out a detailed survey about my entire family in the hopes of getting some coupons for laundry soap, so I cannot judge. :)

The comments you're bound to receive as they relate to this comic remind me of an older one:

Maybe I'm wrong and BI readers aren't that predictable.

Maybe.

My answer:

How often we visit the site every week. That way, you'll know who's hardcore.

THE DETAILS ARE UNIMPORTANT!

I guess it should be hair color.

I guss the it would be interesting to find out what percentage of your readers are female, my guess less than 7.5%

Um... Stuff.

demographic data eh? well i have 2 kids, am 41 years old and household income of approx 75k a year, which is workable only because I live in Iowa, and I don't always drink beer but when I do it is American, cheap, cold and flavorless. Been reading the comic for over 3 years both here on the blog and on my goComics feed (I like the comments so much, I read both sets)

Based on this mind blowing article:

You should be asking whether we sit or stand.

P3nis extension cream, does it work?

Hair length

This comic is not as funny as the one that was funnier.

Well, one of the most obvious pieces of business data would seem to be our proclivity (or willingness) to purchase your books and shirts.

For a technical level which web-browser we use could be interesting to look at (before being completely discarded because it's useless), though, thinking about it that could be a good comic similar to your "How to choose a smartphone" one.

Also, asking us what our favorite strips are would let you put together a "best of" coffee table book, which would net you more money be re-recycling your existing work.

A fun one might be what conventions we attend so you could decide what would be worth it to go to as well.

How about this - Are you a Demograph, Republishing or Independspants?

You should be finding out how many of your readers are bald guys with goatees. And if so, how many of said bald guys with goatees have used your comic as a facebook profile picture.

Here are some relavent demographics from me:
Five.
No.
Only occasionally if it has chocolate on it.

NGAAA!!!

The most valuable demographic data is the number of readers who are currently using 12345 as their password AND the combination of their luggage. Knowing their addresses might be helpful as well.

Obviously, you should be asking us our height.

Good luck, Scott!

I want a book!

I love the link. For those who haven't taken the time it is worth checking it out. It's brief and well stated about people you initially like but eventually avoid.

"Are you often startled in a room full of fish?"

"silence"

This should help you figure out how unwilling we are to answer survey questions seriously.

Dogs. or Cats. Or both.

You should be collecting whether we set the toilet paper to roll over, or under.

A useful demographic to collect from your readers is the age we act (vs our actual age). I'd suspect we skew low. :P

My answer is: yes.

Oh God, do I have to explain it??

It means I think asking our opinion on what demographic data you should be trying to gather is a good enough demographic-data-gathering.

Do you ever show up at conventions like ComicCon?

I like chocolate!

What kind of demographic data from us coudl you possibly want to know that you don't know already? I mean we're skewed toward middle-aged, overweight men with impeccable senses of humor and taste who probably buy too many electronic gadgets on impulse.

I would ask how many of your readers are single women in the Denver area who like to date guys who comment on web comics.

Ask how many people have shaved their heads and grown a goatee since finding your comic.

Through Facebook I'm pretty sure you can pull my HID (That's Heavenly Identification, given to your soul at the time of the creation of the universe. Don't ask for the card, the line is killer.), and my shoe size. Both of these will be necessary when you purchase my soul. (Cheesy pun drum crash)

Location and Spending Habits.

I mean, if you knew what I spend my money on, then you could tailor your product to suit my tastes more (not that it needs more tailoring of course)

By the way, I love Jenkins, his strips are the best.

Well, actually THE DETAILS ARE UNIMPORTANT !

How many of us would be willing to have sexy time with you?

SSN, credit card number, and PIN. Or rather, gullibility.

You should ask, "Toilet paper -- over or under?"
