+- Every website or web application is one star in this space.
+- There are many combinations that work well. While others no so much.
+- We all plot our path in this space. And have our current home there.
+- There are clusters in this space, i.e. the React-Cluster, oder Angular or Vue.
+- My current home is in the L-O-B with Go and Vue vicinity.
+- There is an old Cluster called Hypermedia. Where all Webapps once lived. 
+- Hypermedia has developed a new bulge called HTMX.
+- Next to it is a new tiny blob, called Datastar.
