I certainly prefer real data, and it's an interesting idea to make the poll. One unavoidable problem though is participation - I think the people who didn't get their coins are much more likely to vote than those who did. Many people who did will have got their reward, forgotten about Authorship, and moved on to other coins. But people who didn't are more likely to still be posting in Authorship threads.

So I do think the end results will be skewed and give a false picture.
