catch-all is good, but you need to be careful of not creating overlapping categories - surely, things like gear/tools etc, will have (for the uninitiated) a large overlap with tech, as much of our gear is tech.
when discussing programming aleph is that now gear or tech?
Id agree with this…
I ‘up voted’ modular, as I suspect there are quite a few non-modular users out there … and its not just about GAS suppression 
however, I do recognise that monome, now, probably has more eurorack users now than non, so perhaps lines therefore is focused on modular users, so perhaps Im in a small minority here.
should monome modules be in ‘modular’ or monome - that already seems to be in question, some discussions are in monome, some in tech… its an overlap, so is ‘bound to happen’.
categories are not perfect for this, tagging is better … which discourse also supports, but when I added tags on another site, I found most users did not use.
