Hello. I'm new so forgive my ignorance of previous ideas.

[John Kipling Lewis]

One thing I thought might be useful for Markdown was logic that converted 
certain text to <del> tags.  Since Markdown is often used as a way to 
transfer information from email and there is a convention for simulating 
deleted text in email it might make a nice addition.

Example:

I really love^H^H^H^H hate you.

becomes,

I really <del>love</del> hate you.

Thoughts?  Too specific?  Too geeky?  On target?  Nice Easter Egg?
