The plan is to build the site into some sort of Netflix for Java. I.e. handle a range of topics, be it plain Java Stuff like Optionals,Stream,File API, etc. etc. on to more advanced use cases with frameworks like Hibernate, alternatives such as JooQ, Build Tools, Maven+Gradle, handle distributed computing etc. etc.
That being said, I do have a backlog and if you want to see a topic sooner, rather than later, you simply have to send me an email
