Moritz Stefaner's Notabilia [notabilia.net] reveals the sentiment within the community discussions that focus on keeping or deleting specific Wikipedia entries. Any Wikipedia editor has the power to nominate an article for deletion and, if this nomination is legitimate, a community discussion takes place where follow editors have the opportunity to make their voices heard.
The online visualization visualizes 100 Article for Deletion (AfD) discussions that took the longest amount of time. A discussion is represented by a thread starting at the bottom center. Each time a user joins an AfD discussion and recommends to 'keep', 'merge', or 'redirect' the article a green segment leaning towards the left is added. Each time a user recommends to 'delete' the article a red segment leaning towards the right is added. As the discussion progresses, the length of the segments as well as the angle slowly decay.
Note that the visualized subset might not be representative, as more extensive data suggests that the largest part of these discussions ends after only a few recommendations have been expressed.
