For all who have posted since June 20...
The contest is over. I posted a comment about that on June 21. ICYMI:
41,240 comments in total. Although muneshyne21 guessed 41K, he had the advantage of posting as the contest was closing, so I think Jonas_H's guess of 47K was much more prophetic.
My own guess was way, way, way over. I didn't take into account that as the contest announcement moved further down the news feed, there would be fewer and fewer new comments added.
Nonetheless, according to Dan Rubino, we managed to take down Mobile Nation's CMS servers a few times and did so without any malicious intent. So that may be something we can all be proud of.
I didn't win the Surface Pro 3, but if I can focus on work and not be distracted by WP Central too often, I'll be buying one soon. GLe1 on the Hidden Gems contests!
