From my understanding it's a video twitter, where people can post at maximum 6 second videos of what ever. I personally don't think that there is much of a market for posting 6 second videos or watching them but I don't even watch TV so what would I know. It is aimed at smart phone users and tablets as I am lead to believe. It can't be used on a desk top or laptop, mobile only service, App based. I only use a desk top so what would I know about the habits, wants, wishes or desires of such users. To add to this I am not young either and who knows what madness young people might latch onto in their hormonal brainstorms. I can't be bothered with FB and I am not a Twit so it might as well be Martian to me as most of it is anyway. I want to get away from mind clutter not add to it. It's all brain box pollution to me the lot of it and social distraction, not anywhere near real interaction.
