After having been confused by the retagging of winforms no less than twice in two months, I would like to request a little bit more restraint when retagging.
The criteria for some retagging requests seem to be somewhat arbitrary. Retagging threading to multithreading for example seems to satisfy the pedants who prefer the proper term but goes contrary to the prevalance of the popular usage of threading. I would propose that it's important to consider what people are most likely to enter into Google when looking for answers about a topic than having the one true tag that satisfies a particular persons need for order and cleanliness.
Secondly, I would like to request more care to be taken when retagging is done. With the winforms example, I had added winforms to my list of favorite tags. Then, one day, I clicked on my winforms tag only to find that there were all of 3 or 4 winforms questions compared with the thousands the day before. I dutifully updated my favorites tag to the prescribed windows-forms and was again on my merry way. However, today I was again rudely awakened by my windows-forms tag only reporting a handful of questions; the windows-forms tag had been reverted to winforms. On the first pass, I was completely unfamiliar with the retagging process and it was quite confusing to me.
If retagging must be done, please update these related things as well to streamline the user experience.
