# The Sinatra app behind http://clickthatbutton.com/ running on http://heroku.com

# I can't figure out how to increment the "clicks" counter and get the db to return 
# the new total without doing another request... holler if you know how...
# I tried to use Sequel and ended up getting pissed off somehow, so reverted to
# using Active Record and laying in the hammock.
