Hi Ryan,
First, thank you so much for the interesting feedback... I will learn plenty with this thread I am sure.
#1 Interesting tool validating the html... I am kind of surprised by the errors since the html is very basic. I wonder if it's finding issues with my Masterpage. I will dig in and see if I can clean those up. I have cleaned up my issue with the Div in the Head... which was hurting every page on the site... very nice.
The last 20 errors seem to be a complaint with microsofts image map. Or at least, I need to set noHref somewhere on the image map but I dont' see the property. I will work on that.
#2 I purposely used the singular because that is the exact keyword I want to hit. I figured taking the slight hit for grammar was better to get the exact keyword. I'd be curious to hear your thoughts on that trade off or if there really is a tradeoff there.
#3 Yeah, I will be adding some content but not much... the star of this page will be the notes and the breakdown of their anatomy
#4 The note is an image map and I have defined 12 clickable areas on the image where a tooltip will show on click or hover. I thought describing the click to a site user was a little more intuitive than having them hover over. My users will tend to be older.
#5 Fixed.
