I have recently wrote a few questions for Gerrit code review system and with each question being written, I could clearly see, that only git tag appears among suggested tags:
The gerrit tag has now over 400 questions and I put that string in many places in my question, but even though it doesn't appeared as suggested tag.
So: what conditions must a tag meet to become visible among suggested tags?
For past five-six questions about Gerrit, git was the only tag that was visible among suggested tags. A few minutes ago, I've asked another question about Gerrit, and this time I saw whole bunch of suggested tags, including: git, svn, merge, github, and version-control, though neither GitHub nor SVN haven't been mentioned even an once in my question.
As in above, just added new question, this time for Notepad++ and notepad++ tag wasn't among suggested, though it has 1800+ questions tagged and though this name is mentioned few times in question body; on contrary, html and css tags were suggested, though there isn't even a trace of them in question body.
This case (my question) becomes more and more interesting...
