I was recently downvoted for accidentally posting content that had already been posted. Since then, I have come across a few interesting news items that I wanted to post but refrained for fear that the content had already been posted. My concern now is that other users may also periodically refrain from posting interesting content thinking that it may have been posted already. This wouldn't be an issue if there was a simple text search so users could easily determine whether their content is new to the platform before posting it.
