I share the latest releases of Human Side of Dev on both Twitter and Mastodon. Currently, Mastodon makes up about 56% of traffic, while Twitter is 34%. With the recently announced changes, I expect that second number to drop.
I find this interesting both because I have significantly fewer followers on Mastodon, and because the timeline is only chronological. I feel like the correct decision is to focus more on interacting on Mastodon in order to build an audience for the show.
