Hey everyone, I'm the person who made the announcement on Reddit this morning. I can assure you that we did not go ask anyone to give us that question. But, did we know someone would? Of course. Every single blog post we've done for the last year has asked about it. If you look at our twitter account, it only took one minute yesterday after we announced the AMA session for someone to ask. We thought it would be a fun thing to do for the Reddit community.
I love what you did! Of course it is set up, as you say, by waiting until someone asked the question. But it's refreshing compared to corporate-speak announcements that we tend to get bombarded with ;).
