As previously referenced in the recent post about closed questions, many questions pertaining to mining are being closed as off topic.
I think that much of the confusion comes from ambiguity in the on-topic list. In particular, are questions pertaining to mining in general, but not to Ethereum in particular on topic? For example, this was given as an example in the aforementioned post, but I would argue that nothing in the question mentions or is specific to Ethereum.
Many similar questions are posted, asking for hardware recommendations and expected hashrates and help with mining software like Claymore, and I think it would be good to clarify whether these sorts of questions are on-topic, perhaps by expanding the category
Open-source Ethereum clients, wallets, browsers, or other related tools and libraries
to include mining hardware? What do you think the litmus test for these types of posts should be?
