Any Advice?

Try to find post you are interesting and upvote the good comments. Please don't upvote jokes, unless the joke is very original and very funny.

If you and expert (or semi-expert) in the subject, try to reply to the questions in the comments. You can try to add your own questions if nobody else had asked them.

Don't write short comments. They should be at have at least three or four sentences. This is not a hard rule, but you must know very well what you are doing to write a oneliner. (Very long comments that are a wall of text are also bad.)

To write the comments, you can use https://translate.google.com/ or try to fix all the wavy errors in the browser. (Your English looks good to me.) It's not necessary that the comments are perfect. I try to fix all the errors but when I read my comments later I always find a few obvious errors.

There are some official advice in

My favorite part of the official advice is

> The most important principle on HN, though, is to make thoughtful comments. Thoughtful in both senses: civil and substantial.

And there are some unofficial collections of secret features, but I think this is enough material to read.
