I would agree that the warning is pointless and while I don't follow specific tags personally I don't see warning as being useful to anyone. I support the idea of eliminating warning entirely and have managed to edit a few but ran out of time.
The tag usage guidance:
Goes often with "log" or a name of a program that gives the message. Is usually a symptom of a problem, and for some, the only thing they have by which they can search for solution.
It is just really unnecessary for people to tag questions as messages; they might have a log message, but in that case they should use the log, so ...
There are so many things blocking can mean, and if we allow this tag to keep existing, it's sure to take on even more mutually unrelated meanings. (Blocking I/O, ...)
As Jorge Castro says, "Kill it with fire!"
Since /var/log/messages doesn't even exist by default in Ubuntu (14.04 & 16.04 checked) I don't think the log argument is a relevant reason for retaining this tag.
The only possible use for this tag that I can see is if perhaps someone is looking for how to send a message (or messages) to another user, terminal, or system. Perhaps they are looking for ...
I'm not sure where the ip address tag should be used. I know what it means, but I feel that all the possible topics are well addressed with the networking and related tags. There have been questions about using ip addresses range with iptables, something that doesn't have to do with the underlaying internet protocol but just with the functionality of ...
We need those tags.
cd-burning is about bruning cd's and very often includes making music cd's
dvd-buring is about burning dvd's and often includes making dvd videos
Tasks that followers of either of the tags would want to keep seperate.
Unfortunately we aren't allowed to "tweak" tags without creating a new one and synonymizing, but we're also not allowed to create tags that only differ by a hyphen so Migration of tags (live-cd, livedvd) is your only hope ;)
No. ARM is a cpu architecture, ubuntu-on-arm is a distribution of ubuntu made specifically for arm. We don't take ARM (the CPU architecture) related questions but we take Ubuntu running on ARM questions. ARM should be removed and questions retagged to ubuntu-on-arm where applicable.
There are couple of questions about installing ARM related tools, those ...
I think we should merge them. The people saying we should destroy them, what if the people are asking about Kubuntu, or similar distro's to Ubuntu. (I, personally, count Kubuntu, Lubuntu and all the other "untu" distro's as seperate fom Ubuntu)
Maybe their asking about the differences between Fedora and Ubuntu. These tags would apply. So, why destroy them?
