Spoiler, its RDT
In case people do nto know what RDT is, which they really should if they have been into coffee for a little while as it makes a big difference:
RDT is Ross Droplet Technique, which is very much adding water to beans. Named after David Ross who came up with it back in 2005
Its an extremely basic beginner technique, one of a handful that any beginner should learn right at the start of their coffee journey. I would be embarrassed for anybody who has spent time in the hobby and not come across it as its been around since 2005 and is heavily promoted. Its regularly mentioned even tangentially in grinder reviews FFS.
If this had been a post to the technology or science communities I would have posting a more detail explanation as the audience cannot be expected to know much about the topic. However as this is posting to a specialist community I would have found it massively patronising to do so.
Assuming a specialist audience doesn’t know what you are talking about is worse than assuming they do. Its common for people who do not understand the context or detail in a post to ask for explanations, and they usually get answers across a wide spread of communities. Its also extremely entitled to act like a massive dick when asking a question and given the answer.
Edit: Ill also point out that the answer to what RDT is even if it doesn’t name it as such was also in the article linked, and its not a long or technical article. Very clear that the person in question didn’t even bother reading the article.
