Quick summary
Bluesky, the social network, has added direct messaging to its app and website. You can block messages from strangers or allow anyone to contact you.
Since Elon Musk took over Twitter there's been no shortage of supposed Twitter killers, but so far the renamed X.com remains very much un-dead. And a big part of that is because its rivals have lacked key features, such as the ability to message people privately as well as publicly. So the arrival of direct messaging on Bluesky could be a very big deal.
