Nothing like a tip I use the instant I read it. I've been struggling with an extra large PDF version of my slide presentation (I had to use PDF because Apple uses Quicktime to compress images, resulting in images that can only be seen using Apple - which, btw, is evil). This post points to a little-known way to reduce the size of PDFs using Apple's Preview software - hidden, for no apparent reason, among the colour filters (this sort of obfuscation is also evil). Tried it, and converted my 56 megabyte file to 4.7 megabytes. Why, I wonder, wasn't this compression available in the application that wrote the PDF in the first place?
