I am somewhere in the middle on the formal/fun discussion. I have an old fashioned business ethic - the whole "you wear dress clothes to work and no open toes or sandels to work" kind of lady so I am a bit uptight about this. My website will have a professional photo of me and then my blog or newsletter will be a little more laid back with a picture of me and my dogs. Same thing for my title - on the pages other than the blog I will be listed as the owner but on my blog I may be listed as the chick in charge or something a little more fun like that. ;0)
