Agreed things have reached that point now. It might get a little sticky which things would be posted under ‘monome’ or ‘modular’, but it makes sense.
I like the idea that the bar for whether there should be a new a category is whether there’s enough noise that an uninterested party would want to hide that category.
Final point though - is ‘modular’ sufficient? perhaps ‘modular synth’? Trying to make sure the nomenclature makes sense to the uninitiated who are perhaps more likely to want to turn off this category than initiates.
