Slack is killing emails.

Nextdoor is killing Facebook.

Verge is killing journalism or what's left of it.

In reality Slack had only 150K users. Nextdoor is barely known outside of few neighbourhoods (sure, they can claim 1 in every 4 neighbourhood has "adopted" Nextdoor). Lot of articles from Verge getting posted here recently smells a lot like just paid PR stuff for startups. They are almost like informatials on late night TV. Take everything from them with huge pinch of salt.
