What a world we live in.
For those asking, I assume this is someone who read something I wrote, probably the New York Times letter, then visited my web page to find something to hate on, clicked on About, and saw this at the bottom of the page.
@ct_bergstrom Gave you the chance to fix the typo on "acknowledgement," I see - every hate-spewing cloud has a silver lining, I guess?
@egrets Yes! Fixed it now.

In US English, the preferred spelling is acknowledgment while British prefer acknowledgement. Both are correct.
