Hay it's fun handing out business cards and seeing double takes - there has to be some reward to working for nothing at the moment. I must admit it felt a bit silly at first, but I preferred it to CEO, Managing Director has a solidity to it I like, which counteracts the nebulousness of IT/Web stuff a bit. Owner / Chief Architect were others I tossed up. MD seemed to be the best.
"General Manager" gives you a lot of flexibility to be what you need to be to different people. If you're CEO, COO, etc, it's harder to say during a negotiation "I've got to check with so-and-so and I'll get back to you" to cool things down. Lower titles obviously convey lower authority for people who want to speak to someone higher up.
