Depending on what site(s) in the network you spend your time on, you may or may not know that Stack Overflow recently spent a long time trying out something called Documentation. One of the features we added to SO for that now-closed project was the notion of tags having a "friendly name". For example, sql-server's "friendly name" might be "Microsoft SQL Server", which allowed a much nicer presentation:
This provided a workaround for a lot of the issues with trying to cram lengthy "official" names into the short, strictly formatted tag name—even after expanding the length of tags from 25 to 35 characters—but is currently unused since Docs is gone*. So rather than throwing away what appears to be a generally-useful bit of functionality, why not use friendly names on the tag's pop-up card:
This question is about not only retaining the ability to associate a "friendly name" with tags, but expanding this functionality to all sites. We're thinking this might be helpful for long product names, titles of books and movies and games, the occasional given name, &c.
The input field for a friendly name would be located on the tag wiki edit page, and accept standard plain text; basically anything a question title could take.
Would you find this helpful? Harmful? Just kinda meh? We're thinking this is a pretty straightforward keeper, so if you've got concerns, now's the time to raise them.
*: Discussion about the Docs sunset generally is outside the scope of this post; there's plenty of that on SO's meta, if you're interested.
