I've just discovered that my newly coded website works in IE6 and 7, and in Firefox, Safari (windows) 3 and Opera 9.
I've also just discovered that the website displays it's content but misses it's footer (purely an aesthetically displeasing sight) in IE 5.5 and it's a complete mess in IE 5.0
My question is, having satistfied around 97-98% of the web browsing world, is it really worth trying to find and implement hacks that make it work in IE5 variants. Would it be unprofessional or unwise to completely ignore them? (ideally of course, I'd like the site to reach everyone that would choose to visit it, and in the same way, but would that be unrealistic?)
