Is it possible to downvote a submission? Do you mean flagging?

That doesn’t seem appropriate for something that’s simply uninteresting, based on the site guidelines:

> If a story is spam or off-topic, flag it.

Uninteresting is off-topic, per the guidelines. “On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.” (emphasis added)

When you have 500 points you gain the ability to downvote.

That's only for comments, as far as I can see you can't downvote a submission
