After you've typed in a question, you get suggested tags that appear that look like this:
It appears that you need a minimum amount of characters (much like the limit on 'Similar Questions' in the right-side pane):
you must have entered a title (any length) and a minimum body length of 220 characters.
But other than that, how are the tags chosen? Is it:
- A match of the title/body with other questions (taking the tags from those questions)
- A match of the title/body with tag excerpts (taking tags with overlap)
- A match of the title/body with tag wikis (taking tags with overlap)
- All of the Above
- None of the Above
- Other (please explain)
Some additional info from a previous feature request:
The suggested tags seem to only pop up on meta.so (they do not work on regular Stack Overflow, or on other SE sites).
While we're on the topic, why isn't this feature implemented network-wide?
