Wasn't this posted yesterday?
Yeah. It's hard to not duplicate links when there is no search yet. I'm sure that will come soon enough, though.
It would be ideal if the site could detect that the same URL has been posted in the last week and translate the new post into an upvote on the prior post.
We show a warning that says something like "This was posted 8 hours ago, are you sure?" when you're about to post a duplicate.
What we should be doing is disabling your ability to post if you hit "Yes" when prompted with the above message :)
dont hate, litigate.
