There are a lot of tag wiki excerpts that are in the style of:
Questions about/specific to <tag-name>, <description of object>.
Tag for questions about/specific to <tag-name>, <description of object>.
Do we really need these trivial elements in front of our tags?
We don't, it consumes the limited excerpt space and adds no value at all.
On closer inspection of the tag list it seems several other tag wikis also contain meta talk that's not directly related to the tag, or unnecessary bits like this.
For example, let's take the excel tag, it has this excerpt:
The Excel tag is used for referencing the Excel spreadsheet application from Microsoft. If your question is about VBA then also tag it VBA. If it is about an Excel formula or worksheet function, then tag it worksheet-function.
and the same is used for the tag info itself.
This really tells us nothing about Excel other than that it's a spreadsheet application from Microsoft. And why do we need to be instructed there for each other relevant tag that we should tag it such way?
Painfully meta, with basically no useful info on the topic at all!
Now compare that to the most popular tag c#, which lists what the tag is about in detail and doesn't contain any painful meta information whatsoever. It doesn't tell me about relevant tags because if I create a question I already know what it would be about.
I don't have to be told that my question regarding a problem with a controller on my website needs to be tagged c# asp.net-mvc; even better, I will not read the tag wiki or excerpt at all when creating a new question. As that's not the place where tag wiki's and excerpts are often read, they are read when we go to a specific tag or search a specific tag and sometimes when we hover a specific tag.
Then why is this information needed at all for a tag like excel?
Now, don't get me wrong, there are plenty of very good tag wiki's, and I'm sure they form the majority, but there are a few like this that a quick glance at the first page or two of tags turn up.
I believe that there is no place for meta-data in tag wikis, nor should the very space-limited excerpts contain any irrelevant filler text that states the obvious.
What does everyone else think?
And if there's some agreement can we please all start getting some of these tidied up!
