Right now I'm using very basic classification:

1. is this topic "technical" (ie. Directly related to the day job of a software engineer, electrical engineer, computer engineer, computer science). If so allow.

2. Does this topic give advice on how to drive GTM? If so allow.

Everything else I'm hard hiding so it is somewhat lossy, but I don't need to read discourse about zeitgeist about "VC" or politics from random HNers who don't know what a vintage is or what an LA does.

I could go more precise with my rules and filtering, but it's good enough for me.

I haven't thought of a solution for account filtering yet though and some accounts (a couple of whom are on this thread as well) are deeply aggravating.
