Some comments on the mockups:
- Image via nearby - Looks good
- Add/edit lead image to the article - Reasonable, although it might be a good idea to surface images from commons before uploading
- Moderation queue for image submissions - Addressed in another post, but mockups seem reasonable. Make sure not to surface other user's moderation (e.g. +1 / -1), as this may cause bias and bad moderation, e.g. most experienced editors are negatively biased towards new contributions (despite claiming or believing that they aren't).
- Lead image editing - Good concept. Looks uncontroversial, and easy to revert.
- Article Feedback - This is complicated, +1 or -1 votes may be inaccurate because they may refer to a prior revision that changed wildly, may make people vote on the topic and not the article, and may cause issues.
- Downvoting regardless - People against the theory of evolution may "downvote severely" despite the quality of the topic.
- People also don't read instructions - This is better done indirectly, for example, if an article has lots of spelling /grammar mistakes, incorrect information or is unintelligible, then the user is basically noting that the rating is low.
- It is considerably harder to identify a good article.
- Wikilabels, wikigrok - This seems good.
- Report an issue
- The good : Nice implementation of taping the problem directly, and structured problems.
- The bad : Again, freeform input is a problem, it is better to focus on common issues and add onto them later than allowing free form and dealing with the endless drama and headache with "i hate Puppies" or "No, the true God is ..." kind of comments. Structured comments don't need any moderation, and will not place an extra burden on editors.
