I don't see that the sites assume a person has effectively unlimited time to build up karma. What I see is that they aren't interested in the participation of a person who doesn't.

And "unlimited" is an exaggeration, isn't it? Isn't the actual amount of time quite bounded and even predictable?

Computer networks used to be full of communities like that. I used to read and contribute to several forums every day. I knew most of the participants and we discussed things I was interested in. I had to stop when the Net got too big and all of them turned into help desks. I can understand people trying to set up such a community again, at the expense of the occasional quality contributor who just drops in.

the time needed to earn karma may be bounded on one system, but across multiple systems it's not.

in part it depends on the karma system

one system I know of won't let you post anything in the dev section until you have posted enough messages outside of that section.

people can post stupid messages to reach the count, or they can wait an unknown amount of time until they have good useful messages to post. how long is this going to take?

requiring that people build up karma eliminates 'drive by' assistance from experts along with 'silly questions' from newbies. If you are doing kernel development (especially reverse engineering odd hardware), wouldn't you just love to get a comment from Linus? A Karma system will prevent this, and I guarantee you that your walled sandbox is not important enough for him to jump through hoops to participate in.

one of the criticisms of contributer agreements is that they raise the bar to contributers by making the process of submitting a quick patch hard. Karma systems do the same thing to block contributions.

I agree with all that, but I don't think the folks who invent and deploy karma systems make any false assumptions. I think they make a conscious tradeoff.

Just like when people have spam prevention systems that make it difficult or impossible for some people to send them email. Or unlisted telephone numbers.

or requiring contributer agreements for patches.

or requiring copyright assignment for patches.

why is it these last two get people up in arms, while these other limits to contributions are shrugged off as not mattering?

Because with patches, you have already limited the set to those that can write patches.

Regular forums on the other hand need to filter out many more people since the bar otherwise is only the ability to enter text into a computer.
