There have been discussions on the usefulness and visibility of Tag Wikis. Two concerns that were voiced were :
I had some ideas on how to tackle this.
Making Tag Wikis searchable should not / would not be a very difficult task. They are indexed by Google, so they are searchable externally.
I think they should be made searchable similar to questions and answers internally as well. In a search query, the tags should first be identified, and then the remaining terms could be searched for within the Wiki. Then, questions and answers could be searched normally. If the Tag Wikis are well written and curated, they would have the FAQs of the tag and some of the commonly asked information as well, making the search process possibly faster and return relevant results.
Tag Wikis are a minimum 3 clicks away from the home page whereas questions and answers are 1 click away. This itself is a demotivating factor as far as putting efforts into the Tag Wikis are concerned as compared to asking and answering. Moreover, the chances of a new user even stumbling onto the Tag wikis is remote.
To tackle this, Tag Wikis could be brought right onto the home page. Clicking on a tag from the panel on the home page would redirect to the Wiki and not to the tagged questions. This would be only from the top panel.
The tags that appear on the top panel would be ones that are selected via a democratic process by the community, and not simply the most popular ones. This would allow for the site's best Wikis to be displayed on the home page.
