I jumped ship, and the friends and family who are important to me are still on the ship, by and large.

Yet I've never felt as though I'm missing out. We communicate via alternative forms (texts, calls, hanging out in person) and I have never felt disconnected.

The whole trope about people being worried about missing out is misplaced - that feeling is exactly what these products are designed to imbue in their users. Ultimately, if you value others, you'll make the effort to connect somehow, and if they value you, they'll return that energy. If that two-way street doesn't exist, if they're not willing to give back a similar effort, then why do we need to know what they're doing or thinking every day?
