I removed the tags from that post – is rare that topics here need tags and then only at most one or maybe two tags that can be used on multiple topics without confusion. This topic is a good example of tagging, ironically…
But I too noticed a few other topics had the same combination of odd tags shown – I also removed that particular combo of tags from another topic not pictured above.
I think this is the safest way to ensure it doesn’t get out of control.
True, we have members that will select inappropriate and / or too many tags for their topics, but that isn’t as bad as it would be if they could create their own.
I would agree to @codinghorror, I wonder why would people add tags when the category name itself is self-describing. Multiple Tags never helped any way in SEO either, they are just for better user navigation and only when you use at most 1 or 2 tags. More than that makes no sense
