>In the meantime, I think Snapchat's marketing angle is ingenious.

IMHO it's not something very ingenious, they are shooting ideas - some of them stick to the wall.

> They <...> built trust in the community of shameless consumers

..and that's why the idea sticks (just like whole snapchat et al.). It's shameless and to put it more straight - frequently egoistic (and maybe arrogant as well?) users who use this and go crazy about it.

With google's glass the media raged about how it's a huge privacy problem [&]. Snapchat's spectacles? Genius!! Short memory.

[&] Though to be more critical, having a huge price point and available to few people was the problem as well, but IMHO the media sunk the ship before it was a float by labeling it as a huge privacy issue.
