On Reddit it depends on how the karma was obtained.

Example questions:

- Did they gain all their karma in one post, or was it gradual? Gradual karma is better because it implies that they're probably not a troll.

- Did their karma come from the current subreddit or a different one? Just because you have karma from a popular sub doesn't mean you're a good contributor to a niche sub.

- How frequently are they downvoted? Frequent negative karma in even-handed subreddits is a bad sign.

- Does the user have good reputation in related subreddits?

So it's usually not the number that matters, but the context around that number and how it came to be. That said, usually these things only matter when a user is misbehaving: if you're a mod you need to know whether they're having a bad day, or if they have a history of breaking rules and trolling.
