And definitely put a karma requirement for polls.
Another idea is that posting one article a day could be free, but ti costs karma for each additional one posted (maybe even an increasing cost based on how many you post per day.)
Requiring that users acquire at lease one point of karma from posting comments before they can submit stories would also eliminate the random floods of spam submissions, since spammers aren't likely to either (a) post comments, or (b) have the comments they post get voted up.
Requiring that someone has SOME positive karma before posting is just a way of saying "yes, this person has shown some interest in participating in a reasonable manner".
I think the problem is that it's easy to vote up quick amusing little things, but longer submissions that take effort to read, understand and evaluate have a bias against them, so crap tends to float on top.
For me a poll may be a replacement for some of the Ask YC threads.
I like the way it is now but for those who are worried about karma ¿? maybe the best solution is not getting karma for submitting a Poll, of course that would need a better place to search for polls, should YC add a poll link to the navigation menu?
But beware the posters with many accounts, for these "Karma Chameleons" just come and go.
I guess this is another case of the general issue that the people who write comments have different characteristics than those who hit the vote arrows.
After that a bot could send the results to all the news aggregators and vote it to the top on all of them, besides seeding the storm and nugache emails.
Finally, it would send the author's IP to Anonymous.
That should effectively dissuade someone from posting lame polls. If not, anyone elso got any ideas?
