Social network "7 hands". How important it is to do everything on time.

At one time, almost immediately after the appearance of “My Circle” (or maybe as before), an extremely pathetic network, “7 hands” , was announced. I remember waiting for her appearance with impatience.
For an extremely long time, registration was only by invite. And it was here that the main mistake of the creators of the service was entrenched.
People love intrigue, but they hate waiting too long. A free registration has opened relatively recently. The moment was lost.
I managed to get an invite in due time. It was a rather interesting idea, I decided to observe what the result will be. Even found a number of friends. We established connections and ... after a while, when the engine was updated, something broke. That is, if you look at the list of "friends", then it is empty. But it is worth going to the page of the person with whom the connection has already been established - voila, it turns out you are familiar!
Now the system provides some unintelligible interface, an extremely limited number of participants and, it seems to me, at best, it will always be in catching positions. At worst, it will safely shut down.
