Well it turns out we have these two apparently very similar tags. I've included their tag wiki excerpts:
event-travel × 19 Travel for the purpose of seeing or experiencing a particular occasion
events × 5 Occurrences and happenings, usually set at a specific, limited time period.
Until I just retagged a Marrakesh question no question had used both of them.
I've always been of the opinion that it's redundant to include the word
travel in our tags. It's like including
programming in tags on Stack Overflow. So I prefer the latter tag even though it has fewer uses and is probably newer.
I think the best thing to do would be to make the newer one a synonym of the older one first so that the original tag creator doesn't get penalized as far as getting badges when enough questions use the tag. But then I would rename the tag to just
events. I wouldn't bother keeping the synonym with
-travel in it, but I'm not sure how tag merging works internally so I don't want anything to break.
Since they both have tag wikis as well as excerpts, some thought should be put in to merging the wording.
