I've been looking at the tag wikis again and I've come across a couple that just seem like dictionary definitions rather than describing how the tag should be used in this Stack Exchange site. Definition tags are one of the things the SE people say is bad and I agree:
Avoid generically defining the concept behind a tag, unless it is highly specialized. The “email” tag, for example, does not need to explain what email is. I think we can safely assume most internet users know what email is; there’s no value in a boilerplate explanation of email to anyone.
Here's a blog post with advice on how to write smart, effective tag wiki excerpts by Jeff Atwood.
And here's a couple of the definition tags I noticed so far:
An animal kept for companionship and enjoyment, as opposed to wild animals or to livestock or laboratory animals.
the act in which a male's penis enters a female's vagina for the purposes of sexual pleasure or reproduction.
OK that clears it up for any of us who were unsure what sex or pets were but does it tell us what kinds of questions we should ask about them or when to use these tags in our questions?
I'm starting to think we should build a nice community wiki question on meta about tag guidelines unless Stack Exchange has one already besides the blog post I already linked to above. What do my fellow contributors think?
