Before HN, I used to hang out on Joel on Software and Eric's Business of Software forums; I occasionally used to post there and here but lost old accounts. If you have friends who have friends who has HN archeology skills and access, maybe I can recover my old account :)
They're the kind of people who consider themselves "tech enthusiasts", they can install a nifty tool via pip if the instructions are clear enough, maybe even figure out what's wrong if there's an error, but they're definitely not programmers by any means.
Quite a few of them speak "tech English"; they can figure out a settings window or a signup form, they know enough tech vocabulary and basic grammar to mostly understand manuals, maybe with some help here or there, and can barely string an English sentence together. Ask them to define "lettuce" or "salmon" and they're lost.
Another possibility is to write the comment in English inside gmail, and let suggestion gmail fix all the errors.
To me that's like 'I love doughnuts, I buy one every day, but the paper bag bits do get stuck in my teeth'.
