There was Great Stack Overflow tag cleanup of 2012 some months (weeks?) ago.
Now this question is deleted.
This was a post that was promoted in the community bulletin, perhaps a more "graceful" removal is needed.
Indeed there was a "call to arms" when the clean-up effort started, in the community bulletin board and in the featured tab, but what about an "all ok" signal once the objectives have been reached?
IMO, if the issue is big enough to alert the entire community, the same awareness should be created once an issue has been resolved (or in this case canned).
The post had accomplished what it set out to do which was get a handle on some of the more problematic tags on Stack Overflow as well as maintain a list of tags that needed to be cleaned up.
Unfortunately, there weren't enough hands for all the work that needed to be done, and the list itself was getting too unwieldy. As a result, there were some isolated cases where people were removing tags without properly vetting them.
Because of these factors, it was better to remove it, as it had served it's purpose for the time being (and what do we do in 2013?).
That said, there are some thoughts on how to continue to do this work while addressing the issues above, which you'll might see in the next few months.
I think it was deleted because it was not anymore relevant, as the tags were all removed.
In his answer, casperOne says that, with a picture.
The purpose of that question was coordinating the clean up phase; once the cleanup phase is over, the question is not helpful to anybody, especially because it just list tags that should be removed, without explaining why they should be removed. If it contained an explanation about that, the question could have been more useful to future readers, who would have understood why a tag should be avoided, and would have possibly avoided creating similar tags.
The history tag still says DO NOT USE and refers to the non-existent post for more information.
While things like browser-history and command-history make more sense as separate tags, I think there is still a need for history as in The History Of "...".
Update: This is fixed now, probably around the time of Shog9's comment. :)
