This is not the "singularity," no, but it is a natural and fascinating evolution of culture in a vastly-more-connected world.
To answer the OP directly, the "singularity" is the point at which technology fundamentally alters how we live. We've technically had a few; they generally usher in new "Ages." Most recently, the Industrial, Automotive, and Information Ages have rolled out due to such singularities fundamentally changing how things go. This community is an outgrowth of the Information Age.
The proverbial singularity, the mythical grail version that futurist philosophers like to romanticise, is actually even bigger. Kind of a singularity of singularities. You'll note that the Stone Age was millenia long, and the Bronze and Iron ages were many centuries each. Since the Industrial Age, we've had the Ages happening over the course of decades. It's accelerating, as technology bootstraps faster and faster.
We're still building on the past, however. Using new tech to advance to still newer, but it's still cascading.
"The Singularity" that futurist philosophers like to discuss is the point at which man and machine are so intertwined that one is actively improving the other. Machine and man become less and less distinguishable, and we reach a point where technology is advancing itself, and we are directing our own evolution through technology. The ways this manifests vary from philosopher to philosopher, from fiction writer to fiction writer, but the core of "The Singularity" is that we are no longer building better tech and still evolving, but rather are using tech to improve ourselves, and our tech is improving itself while we direct its improvements.
