my blog posts are quite old, still think / hope they might be helpful. Therefore I am right now not shutting down the blog. Still to be DSVGO compliant I removed all comments and disabled comment function. Therefore unfortunately good discussion threads are vanished now, a big sorry to all commenters about that! But costs to be DSVGO compliant would have been just too high looking at my available spare time :(
In case you want to get in touch with just contact me directly.
In the long run I will very likely transfer the content to a blog-posts hoster.
