Minor technical correction that twitter can only reach people in areas with internet access, via phone, etc. APRS especially using HF is, quite literally, worldwide without existing infrastructure. This is why the emcom guys do ham radio instead of just packing a backup smart phone. Your point still stands that only about 0.3% of the US population have a ham radio license and less have gear stet up for this peculiar mode.
