Yeah, and to overcome the network effect, you need something compelling enough to justify the effort in the first place. I have hundreds of local contacts on WhatsApp, many of whom have joined Telegram on their own because of its benefits (for example, a local firefighter feed is shared through a channel there). But I only have about 20 contacts on Signal, even IT guys aren’t there. It simply doesn’t offer anything appealing to at least 95% of the people around me.
