Rules must be consistent and unduplicitous. If we handle one tag one way, we should handle all tags related with that tag in the same way (say, all 35 tags about Microsoft products). This might mean that we FIRST have to discuss tag wikis in a setting appropriate for debate and discussion, i.e. a chatroom. IMHO, a meta question is not the right place for debate.
I suggest that to solve the tag wiki issue that I believe to be central to the confusion here, we create one or more tag wiki templates with the following properties:
- Consistent (for example, all tags about software are worded the same);
- Short (they should all be around the same length);
- Supported by the majority (There shouldn't be any discussion after we decided on the wording).
An example for tags related to software that doesn't include the version:
Software developed by [developer name] designed to [goal of the software in 2-4 words]. Available on [list of platforms]. Also see [competing software]
Applied to microsoft-excel:
Software developed by Microsoft designed to create and edit spreadsheets. Available on Mac OSX and Windows. Also see google-spreadsheetsmicrosoft-excel-2007 and other yearly releases.
The main thing to keep in mind here is that we carefully write the tag wiki summary to minimize the discussion about the wording of the tag itself. We shouldn't be discussing whether the tag should contain articles or other contested words, we should be discussing what information the tag should provide to the user. To that end, we should be using a template that states if and where we should use certain words.
Tl;dr: We should use a chatroom to discuss templates for tag wikis so all the tags for a certain group of tags are consistent with each other. Then we should apply that template to all tags of that category.
