Many of your comments are great --- including this one --- but the one Dan marked off-topic was not. I don't know if it was actually off-topic, but it made a sweeping generalization and wasn't a high-quality comment. I read through the threads you linked here, and I didn't see much evidence that 40-somethings were complaining about Snapchat's interface. There were many people who were bemused and confused by it's popularity, but I didn't see any clear correlation with age.
So I think Dan was right to consider your "oogle of 40 somethings complaining about how useless and unintuitive it is" to be a spurious putdown. I think your "first" comment makes the same point about Snapchat's utility, but in a more acceptable manner. So please keep posting other comments, even controversial ones, but if possible avoid such generalizations unless they are well-supported and central to your argument.
