When I visit the root domain I shouldn't be greeted with a marketing splash page, you need interesting content in the user's face right away, entice their curiosity and drive the user to explore the site... even as a fellow developer, my first instinct is to abandon the page as soon as I'm greeted with the cliche startup marketing page. Consider the user experience when I visit reddit.com or news.ycombinator.com or any other link aggregation competitor. What you have now is a tech demo, not a platform. Sorry if that's a little harsh, but I mean well! Good luck!
My original plan was to pay for ~100 users accounts and seed the site with content for a proper launch. Given what's happening today though, it felt at least pertinent to show off the current state and get some feedback.
The balance between splash page on landing / landing on content is a hard one, but I think you're right. I am worried though that without conveying the initial business model, it'll be harder for users to understand that this isn't a direct reddit clone.
So basically what already happens with reddit/twitter/etc but amplified because you give them a direct financial incentive to upvote low effort crap.
I think the problem with karma/reputation systems is that the source of karma are fungible - anyone's upvote has the same effect on the reputation. And this makes it gameable.
A personalized system can solve this by replacing global reputation with user-to-user trust. Now it matters who upvoted - a random bot or a user whose past contributions have been useful to you.
In that system how do you create a ranked list of content for a user to browse? Isn't it going to be very heavy on processing demand?
This is more computationally intensive than sorting by the raw number of upvotes or weight upvotes by karma/popularity.
But I think this is a useful computation - the user can be more confident that the content they is is not astroturfed and comes from trustworthy users.
