Email obfuscation
Finally added my email address to the site, and spent way too long investigating different obfuscation techniques. From a quick survey of the blogs in my RSS reader, it seems that most people go with ASCII encoding or plain old fashioned munging. However I found an article which suggests that several email harvesters will decode those just fine, and since the article is already over 2 years old I dread to think how much better the harvesters are today. Went with a javascript obfuscator in the end, as it should be transparent to nearly all users, and seems like it should be sufficient.
