Not sure if this came after www.stackoverflow.com but it’s horrible!

No mention that you have to pay to get an answer. And, just out of curiosity I decided to go ahead and offer $9 for an answer to my question (it was about my garage door and how it won’t close at around 5pm because the sunlight hits the censor at just the right angle) and the answer was useless (“How about shading the sensor”). Below is the dialog box for my reply. If I press accept then my $9 “deposit” is used up and I accepted the answer. Whack! I can’t wait for stackoverflow for home improvement!
