What's your title on the biz card?
I'm drawing up my cards for future conferences, but nosebleed titles are heady but cause some to suspect you are a small operation:
Owner, CEO, Supreme Commander, etc.
For the wife's biz we made her 'Regional Sales Director'. With a simple phone extension setup, many assume she works for a 'firm'.
What do you use?

Sir.
just depends on the circles you plan to run in...and what you want to do.....CEO is good but sometimes its too much.....I always thought that "Director of marketing"...conveys enough power and isn't an over sell so your biz can look a bit bigger than it may be....
but on my cards it just says owner....just keeping it simple
Chief Enthusiast.
I don't even understand a question like this? So, you are just looking to make up a title to put on your business card to try to impress people? Do you think you are going to hand someone your business card and they are gonna walk away saying, "Wow, I gotta do business with that guy because, look, he's the Senior Vice-President of the Client Acquisition Department!"
Maybe it's just me, but I run my businesses like businesses. Therefore, I have real roles and actual titles that mean something and they differ based on the business entity used. But you know what I take to conferences? A plain white business card I had made that simply has my name, email and a phone number (it also has a title that literally says, "Human Being" and a quote from Grouch Marx on the back)
You know why this is all I carry? Because business is all about interaction and relationships. If I cannot make a good enough impression on somebody that I gotta rely on a business card for them to remember me, I am in big trouble! I have never been impressed by a business card and I can tell when someone is trying to act like a big operation (when they really work out of their bedroom) from a mile away. There is absolutely nothing wrong with people knowing you are a small operation, what's important is how people perceive you and if you make an impression on them (you also have to make sure you are talking to the right people!) 
Just some food for thought. Feel free to tell me to fuck off! 
I give myself a "lowly" job postion for 2 reasons.
1. I think there are too many CEO/Presidents in our industry it just screams 1 man shop
2. You never want to be the final decision maker, you can always blame your superior for not wanting to work with someone or why you had to leave a meeting.
@ jakz I think you spent more time and energy on your 'insightful' post, than I will on the biz card. Have another beer.
As others have mentioned, there can be benefits to giving yourself a reduced title.
I have several different cards depending on the situation or where I'm giving it out at.
I've got some cards that are "Founder," some are "Founder/CEO," and I have very very nice cards that I rarely give out that don't have a title for me at all (has my real personal info etc on it).
Like most things, it's highly dependent on the audience and how they'll "take" what you're "giving."
