Good link, but one rule make me want to strangle the guy:
I ALWAYS design my logos in Adobe Illustrator.
Any logo, even one for a Web site, needs to be scaled for different use. Designing a logo in Photoshop leaves you with a ceiling you may not be able to live with later on. Designing your logo in Illustrator also allows you to “break it apart” and use the pieces in other aspects of the client’s work. It gives you flexibility in how it’s used (outdoor, ads, multi-media, etc.) and keeps it easy to edit later.
ehehe.. though I presume you can translate it to:
ALWAYS design your logos in vector graphics
