@an0key @CatherineFlick @hugh I got a WhatsApp message rather than an SMS from a taxi company the other day.
@an0key @jon @CatherineFlick @hugh There are now at least three instant messengers that do not require you to reveal either phone number or email… Zangi, Keybase and TeleGuard. I try to promote their use with people I don’t entirely trust. TeleGuard seems to be the most popular.
