Yesterday we launched PostOwl as a technical preview.
We posted on Hacker News (https://news.ycombinator.com/item?id=36929830) but didn't get much traction. I'll try again in a few days with a blog post about something specific.
Reddit was quite successful with over 10k views of my posts there on r/sveltejs (https://www.reddit.com/r/sveltejs/comments/15disjv/postowl_inplace_editable_blog_powered_by/) and r/selfhosted (https://www.reddit.com/r/selfhosted/comments/15diu1b/postowl_inplace_editable_blog_powered_by/)
The website has had over 800 unique visitors and over 130 video views. But I've only had 10 people sign up for the email newsletter so it looks like there's an opportunity to make that more enticing!
