Seriously? Another user posted "can't read this; can we get a non-facebook link please" - is that substantive?
Or, are you just picking on my comment because I phrased my concern differently?
Also, "a lot of unsubstantive comments" is false. Two of my recent comments created large sub-threads. Two others were downvoted simply because people didn't agree with my opinion.
So, I think it's fair to say that you're ignoring plenty of "unsubstantive" comments and basically picking on people who you disagree with.
The link is to the announcement of the project. The announcement is a public Facebook post, which seems reasonable given that Facebook developed the project.
