trigger recurring readers, visibility

[hpvd]

Great idea to have all these great blog post also at Github!

1. Maybe you like to regularly trigger people to read new ones, just by adding
   a short comment at the beginning of readme, like:

If you are interested in this topic,
just watch this repository to get notified about new posts.
(upper right corner: Watch -> all Activity)

And of course: give this repository a star :-)

2. In addition, you may show a deeplink to your homepage https://terminusdb.com/blog/category/technical/
   • in the about section in the upper right corner (most people are used to find links to the website at this place)
   • also in readme
