Basecamp Founders Announce New Email Service (twitter.com)

Also Jason from Basecamp (in https://basecamp.com/guides/how-we-communicate ):

"98% of our internal communication happens inside Basecamp."

and:

"We don't use email internally"

Then:

"Coming April 2020"

Is this a loooong lead-time Aprils fools gag??? ;-)

No need, Spike is leading the email race anyway...
