I wonder if and really add value over the more generic ?

These three questions currently using as well as those three questions using (there's an overlap) double with in either case (which is pretty obvious). I am not sure if those two specialized help categorize the questions much better though...

What do you think?

When we consider that MQTT is an ISO standard publish-subscribe-based "lightweight" messaging protocol (Wikipedia) where you can't subscribe without a topic and a topic doesn't make much sense without any subscribers I'd say we should make them both synonyms of .

The one question that hasn't the topic tag has the word topic in the body and the question without the subscription tag has the word subscribe in the title. I see no added value by splitting these two from the hypernym tag.

  • Technically a topic can exist without a subscriber but as you say there is little use to it.

  • Agree with this; until there is a need to differentiate the different questions, just stick them all under [mqtt].

I have proposed and as synonyms of . If you have sufficient rep and score in the tag, please vote on them if you wish for them to be synonymised. Four votes are currently required to synonymise these tags (or two downvotes to withdraw the proposal).

Helmar has now burninated the specific tags, making synonymisation unnecessary now. If the need comes up for these tags in future, they can easily be added again.

  • You know that this skill has limited access as of now.

  • @Ghanima anyone with a tag score of more than 5 can vote; you only need 1250 rep to suggest synonyms.

  • Still we don't have enough people to vote on that. It's gotta be done by SE staff for now.

  • @Helmar I think we do - there are 5 users with an answer score >= 5 (you only need 4). It turns out question score isn't sufficient though.
