Or the alternative is get a decent spam filter. I have email addresses on public sites as actual links and with decent spam protection, its not an issue. Making users decipher your email address or work to send you an email is a barrier you don't want between yourself and getting feedback.
you make an excellent point. Most mailing lists I use have public archives and my email address is all over the web, yet I still feel the urge to obfuscate it where I can. maybe I should be less paranoid.
