Here’s how not to use sIFR.
If you’re going to use any sort of scripted text replacement, for heaven’s sake, only use it where you need to use it (i.e. on dynamically generated text). The above page manages to get it right for the top logo and the footer text, but that’s about it. Mundane, static text such as “Author”, “Recent Blog Posts”, and “Topics” all get the sIFR treatment. And this is supposed to be a “design blog”. Kill me now.
