I talked to a couple up and coming artists who are "safe" from the Tumblr purge over the holiday.
They know Tumblr has shot themselves and is going to be circling the drain really really really soon.
Trouble is they can't self-host (spoons/accessibility/knowledge gaps) and/or are waiting on other, centralized services to come online and displace Tumblr.
Now is our time to shine.
Let's put our weight behind the amazing OSS projects geared towards long-form posts that speak ActivityPub as well as projects like FreedomBone, FreedomBox, Yunohost, Lollipop Cloud and others that reduce barriers to entry and help with accessibility of self-hosted content and giving an individual control of their destiny again.
Even jumping into a community to ask questions or provide feedback is support.
It takes a community to have a successful project and everyone contributes in their own way. From Q&A to docs to code. ALL are valid contributions.
