This is a fair criticism. As we build up a larger data set we hope that more value can be attached to the it and the insights be more indicative of the community. Until then we are just interested to share what we are currently finding with the new primary data we have collected.

We could definitely do with a statistician to help us out and minimise any selection bias, but i think that comes when we increase the amount in our data set by another order of magnitude or two. :)

The article does a good job of explaining your methods of data collection, and nothing in the content suggests otherwise.

I wish more articles on the Internet had this kind of transparency.
