This is one of the main reasons I tried garnering interest around a blogging app idea I had: If you blog with a third party service, eventually your blog will go away due to an acquihire, company shutdown, merger, or whatever happened in this instance (google forgot to renew a domain?). If you want to write seriously with a multi-decade perspective, you need to host it yourself, and I wanted to make that easy to manage for an average Joe. Unfortunately I haven't had any luck gathering interest! Technical people understand the idea but just roll their own using eg Jekyll; and Non-technical people don't get the idea, or dont seem to care.
The idea is here: http://www.splinter.com.au/2020/06/07/chalkinator/
Anyway if anyone has advice i'm all ears :)
