As a tangent, I&#x27;ve found that phone + email are the truly general options across what is anecdotally to me the Balkan social networks. I&#x27;ve also come to realize that everyone views their social network as obvious, and everyone also loathes to download anyone else&#x27;s social network app.<p>But email + phone is international, nobody feels like you burdened them by asking them to get a Google account, and nowadays email and phone is all managed through a synced solution on your phone &#x2F; devices. As a &quot;workflow&quot;, contacting someone via phone or email can feel as fluid as any other app.
