Allow streamers to create and set their own tags. If a streamer has a specific category or tag that Twitch does not have, they can submit that tag "for review." The tag wouldn't be listed for other streamers to use or see, but rather make the stream more discoverable.

Unfortunately, it would likely have to go through the same process as emotes, simply because people would abuse this feature. But I have thought of this myself, and perhaps with approval it would work!

I think this would be a much more practical than having to plead here to the importance of tags and so much less work for who ever is in charge of making tags at twitch.

Twitch is growing beyond being a gamers only streaming service, it needs to embrace this change by giving the creators some freedom and the ability to be proactive.

I came here to plead for a tag that could help my specific stream but this is such a better idea and it would be so great ! :D

I support this completely we need more people to support this and also for twitch to explain why they are afraid to do this, maybe it can help us find a compromise.
