Do we have ourselves to blame, somewhat, post 40K SWF?
Having spent so many years as a K weight Scrooge, I can't not care.
However, I know I have coworkers who don't crop bitmaps, or who created an animated cartoon in a banner ad, using bitmaps, that crawled live.
Once the 40K limit was lifted, some view the limit as so what, and don't optimize.
I on the other hand love to brag about my 20K zipped banners.
