My main personal email (permanent address, essentially), I've got on my website with a minimal brainpower test (essentially "[myname] @ [this domain]") --- but I might get rid of that. My email is in its bare form on a number of READMEs of things that I maintain. I've never had an issue with spam because of it. I use Google Apps for hosting my domain's email.
