I have rejected those edits. However, I've typed in the custom reason, and I'm surprised that these cookie cutter reasons got stored. If it was a miss-click on my part, I apologize.
The custom reason I've typed in was along the lines of: "This edit does not cover Fe - iron as element or material, which is used in magnetic cores, among other places. This tag is stretched and/or misused."
For some reason, we have the soldering and soldering-iron as synonyms. Not all of the soldering is done with soldering iron. I'm inclined to break them up. After that, we could write proper tag wikis.
Lorenzo, thank you bringing this forward.
You are trying to add wiki excerpts to tags that are also common English words. These have multiple and very different meanings in engineering. But you are giving only one meaning in the excerpt. Examples:
iron may apply to soldering iron. It may apply to Fe (the chemical element).
stack may apply to a LIFO. It may also apply to a protocol stack. TCP/IP stack, for example.
tube may apply to an electronic tube. It may apply to a general purpose tube/pipe.
static may apply to static electricity. It may apply to a static variable.
On the opposite end, convolution and noise-spectral-density have narrow meanings.
One of the purposes for an excerpt is that a user can read it and decide whether or not the tag would apply to his question. If an excerpt is too narrow, it can be detrimental compared to no excerpt at all. Perhaps, that’s the reason why nobody was creating the excerpts for those tags for a long time.
I would suggest that you don’t edit the excerpts for these common words that have multiple meanings across engineering disciplines. At the same time, the wikis themselves are fair game, because they are not used on-the-fly for determining the applicability of the tag.
Finally, taxonomy systems are never perfect. I guess, this is a preemptive response to Olin’s comment that he doesn’t believe in the tag system here (or something along those lines).
