@feld @delta I thought the blog post was good, and two points really stuck out:
1) For ease of adding contacts, since you can scan barcodes between smartphones, Deltachat might as well be another Signal or WhatsApp (for how convenient this is). I had to admit that scanning a barcode to add a contact is becoming more commonplace by the day - kudos to #deltachat for supporting it.
2) When migration to another server was mentioned as being so easy, thanks to AEAP - "Advanced Email Address Porting" - that seriously blew my mind. I jumped out of my chair and exclaimed something to the effect of "shut the front door!"
@feld @delta BTW: I just had a quick look in #Conversations #XMPP client, and it too has barcode scanning and showing functionality for adding "Chat IDs" between smartphones.
