Some of these tips are really good (using a CDN, caching on basically every layer, using YSlow), but does the author really believe using FPGAs and ASICs for websites is really practical? I've yet to see one real-world report of people using FPGAs to speed up sites. Hell, I haven't even seen any academic proof of concepts focusing on the merits of FPGAs in the web environment.
That's not to say that FPGA's won't be useful (they could potentially be helpful for real-time ranking and the like), it just seems out of character to mention something like that on a website scalability site. Grain of salt, and all that.
