Steve Souders - The State of Performance 2008 (and a look ahead to 2009)

Mr. Web Site Performance, Steve Souders, put together a really nice "review of what happened in 2008 with regard to web performance, and [his] predictions and hopes for what we’ll see in 2009." Check it out at Steve Souders' blog. He references a lot of tools and services you may have missed over the course of the year, and gives some good advice for web developers (and online businesses).
