Asking pointless questions that can be answered with a simple Google search and complaining about other people's use of language do dilute the thread.

It's explicitly in the guidelines that we don't complain about voting because it "makes for boring reading." Complaining about acronyms has the same effect.

Having to google obscure acronyms and having to guess which interpretation author meant makes for super boring reading.

It is way better when you see a question and answer just below. And bonus point, question and answer teaches others to not use all acronyms they learned in all the random subcultures.

seeing the definition for TFR in the thread is not boring reading because, as you say, it's something I would be expected to look up anyway.
