When a new tag is created, should there be some kind of notification to the user? This could serve a dual purpose:
- To make the user check that this tag is really required. Is it spelt right? Might there be a more appropriate tag to use instead? - See Warning or confirmation on new tag creation
- To promote the creation of tag wikis.
These are both beneficial to the site. Making users think twice about their tags reduces the amount of retagging edits that are needed and reduces noise. Promoting tag wikis means that more new tags would come with explainations, making them more user-friendly for others.
Creating a new tag is a privilidge earned at 1500 reputation. Hopefully the user has gained a feel for the ethos of SO by this point, and is either enjoying being a contributer or is mainly asking good, well recieved questions. The user is probably also wanting to contribute to the site further (even if just to gain reputation), and so it makes sense to me that there should be a gentle push towards taking a little bit of time to write a short wiki for the tag you just created. By no means should this be mandatory, and the precise format of this gentle push is more in the scope of UX guys to think up, but I wanted to see how people felt about some kind of discreet notification.
I thought of two forms this notification could take:
Option 1 - at the time of tagging
Option 2 - after posting
Update: Raphael has suggested in the comments that this could be implemented as a 10K user tool. While I think that's a good idea on its own, I don't think it should be used instead. I think that encouraging users with less than 10K to complete wikis for their own tags is likely to get some wikis written because there is a sense of ownership over your own tag, and by giving it a wiki you are giving it a better start in life. As with a child, users will want to equip their tag with the tools it will need to survive in the big wide world.
