I often get messages via the form at http://www.torontomike.com/contact.html. Here's an interesting one I received moments ago.
Dear TM,
I am a strictly anonymous person who wonders why fred's site isn't blocked by my work filter yet a certain other blog is...
I wish to remainameless.
Yours Truly,
Remainameless.
Remainameless, I need more detail. I'm betting the Fred you refer to is Fred Patterson, author of canadianthinker.com, a blog I technically support. Whose site is blocked by your work?
