Every time I mention Wire, someone gets all up in my timeline about how it leaks metadata and that Signal is the most secure. Having to use your phone number is a pretty impressive hunk of metadata to leak, yo.
"But there are workarounds!" If your first response is to suggest a *workaround*, you've ignored the fundamental design flaw.
Of course, neither of them use #IPv6, so it's hard for me get excited about either one. I go where my friends are (firmly entrenched).
@vrsmd I tried to get people interested in moving to Wire. I have three people on my list, and only one I really talked to. Most of my contacts are on Signal. I've got a couple that won't leave WhatsApp, but one is my best friend so I deal :)
