So seriously, stop posting your email address like that. All it does is annoy people who are trying to email you. The href tag exists for a reason: so people don't HAVE to type in your email address.
Okay, enough is enough. If someone has the ability to write a script that will go around the Internet and collect email addresses that have been publicly posted-- don't you think they can also write a script that will recognize the phrase "x AT y DOT com", and automatically parse it into firstname.lastname@example.org?
