Good advice for people who aren't particularly technical when it comes to websites, but I don't think there's much there that isn't already widely known, and frankly could even be learned simply from using YSlow to tell you what to change.
well what the f_ck, a site with "seo" in the url that isn't a massive bunch of crap! It's not as complete as one would want it to be though. A "nothing new, but conveniently formatted" article should be very comprehensive, and at least contain links to more in-depth treatment of each subject.
Mmm... I wonder why you don't write that masterpiece of content about this topic for all our benefit instead of simply shitting all over :)
Wouldn't be the best way to answer to something you feel not useful at all?
Or what you would write would be so totally not useful to be worst than the infamous "How to serve a glass of water" EHow post?
