The attention of the most popular public social networks was caught by private messaging in the last couple of months and, this leads to tech firms that may have a very basic driving force.

The private messaging has the feature that gives privacy to social networks that succeed on openness has been a point of prominence since last month for Facebook, Twitter and especially on Instagram. Other private messaging services like Snapchat, Kiko and WhatsApp have been busy also, sending their own private message, needed private interactions and even in a public platform.

It has long been an argument in the field of social relationships that human beings are only skilled of having 150 social relationships at a time. Users gather hundreds and even thousands of follower or friends on networks like Instagram and Facebook.

The CEO of Nextdoor, Nirav Tolia explains, "Obviously, the majority of people have more friends than [150] on Facebook. You just have to imaging if every time you said something, instead of it being said to the people who are close to you in physical space, it was broadcast to a three block radius. [Think] how much harder it would be for you to have community."

There's a verge for every collecting, and once that boundary is crossed, it pressures guests to break-off into minor groups. This party size of the social media is the result of the advertising efforts to a broader market or narrow-casting the smaller audience.

Although, it is not clear which messaging services are better than the rest, or whether there is an area for all of these platforms to survive. With so many messaging choices, its probable that some standalone apps could be left behind if mobile users more of their discussions to Instagram or Twitter conversations.

On the other hand, that consumers may want privacy and as social networks pursue to grow, the demand for settings and intimate will grow along with them. Tolia further explains, "People are demanding that social media [platforms] support communication that matches their real life experience. They don't want it to feel like email. They don't want it to feel like something that's loaded with a lot of other expectations."
