Given that the OP didn't know about Signal-Desktop 4 hours ago when I told them (see https://news.ycombinator.com/item?id=10750637 ) and was bashing Signal then for not supporting it, I'd say tajzin has at most had a cursory look at it. I'm not sure how or why they feel qualified to blog about it.
I've been using Signal-Desktop since the first days of the Beta and so far it's been a really pleasant experience. Big thank you to all involved!
