The size of your network isn’t what matters. Actually, I’m finding that larger networks are a liability in this hivemind model. Instantly receiving multiple instances of lower-quality information adds so much noise that it overwhelms good signal. And the current algorithms are too primitive to dynamically adjust quickly enough yet.
With this new model, you will want to carefully decide who is in your trusted network, although this creates a challenge for discovery and serendipity (e.g., the Facebook echo chamber problem). This is an important problem to solve!
