I added Postmatic to this site. I also added Jetpack and activated Akismet.
Everything looks OK except that from a different browser where I am not logged in I can only see the Postmatic widget in the sidebar for individual posts and not for the homepage of the site.
Just tested again, maybe ten minutes later, and the widget is now showing in the sidebar. I wonder what is causing the delay? Is it a caching system that ThisIsTap is using?
Slightly annoying because of the time it takes to check and re-check when I make changes.
That said, it doesn’t matter for a test sub-domain. But what if I decide to pay to run a domain?
