Just to play the devil's advocate:

A lot of news getting on sites is PR agencies using their relationships with authors, and trying to get interesting stories out. It could simply be the case that Secret's PR firm is closer to TC than Whisper's.

Of course, ideally all articles would be free of such biases, and would be written and accounted for justly; but I don't think such news-sites/blogs exist.

The fact that it's on Quora is irony in and of itself, given that couple of years ago TechCrunch was flooded with 'articles' about it and how it'll take over the world.

i think many people did so some time ago.

You are referring to my headline? Yeah I was especially patient :)

Secret's just a Instagram/Snapchat/WhatsApp wannabe. Those VC's are hoping as hell.
