Sure. I've had a go and in 40 days have over 700. At 501, you can downvote, which, I guess, is nifty, but it's a pointless (heh) system, so we're really talking about how to write comments people like.

The trick, I've found, is to say things that are interesting, say things that embody conventional or popular thought but are not banal, reference other interesting and similar things, carefully make humor or very carefully make an occasional smart snarky remark (risky, as discouraged). I've found stating controversial views to be poison, and attacking sacred cows to be double poison, so don't rush in to criticize Elon for example. Frame anything you can't cite as your opinions/thoughts instead of as facts to avoid errant critics, and if you have anything controversial that you really want to tackle, hypothesize about it, don't just plonk it down. Make it seem like you're considering all sides so people don't feel threatened.

Also, read the new submissions page instead of the front page, as commenting on a popular well-commented article is pissing in an ocean of piss. You want people to see only your comment on a submission and think "hm, nice comment". Lastly, change your settings to show dead posts, so you can vouch for one now or then. There are some interesting ones, and some inflammatory ones, and many get robotically flagged by default. Many people choose not to see such posts, so you have an edge there.
