The link pages on this site are a simple dump of my pinboard bookmarks. This allows me to search them from this site and ensures I have a backup, but it remains much easier to browse them on the pinboard site (via previous link). Btw, I highly recommend pinboard. They provide simple no-nonsense functionality, the pinboard blog is refreshingly honest and their support is quick, friendly and helpful. It's well worth the small cost. And in case you're wondering, I am not affiliated with pinboard in any way - I just like the cut of their jib!
My latest approach has been the entities approach. The CSS approaches can't be used because they don't allow clickable mailto links (and won't work when css is off). The Javascript approaches can't be used because they rely on Javascript! ATs and DOTs could prove a usability problem. I think the entities approach is the best compromise.
Also, I'm not too trusting of some of his results - his test page doesn't seem to include the ROT encryption technique and instead includes a different CSS technique that uses the same email address as the Javascript buliding test, meaning those results in particular would be wrong.
