Walking stick is almost entirely made up of various types of canes. post #480711 is one of the only examples I could find that wasn't just a cane or mage staff, and I'm not sure there's much value in a tag specifically for a handful of posts featuring a stick being used for walking support.
I've gone through walking stick and removed all the examples of hiking poles I could find, and gave it a simple wiki. If we don't want it we can just nuke it or alias it to cane or something. I think it's distinct enough to be worth tagging though, might be more examples under other tags.
I'll go through again and remove everything that isn't a cane or stick when I have the time.
For reference, wikipedia seems to use the terms "walking stick" and "walking cane" interchangeably, so I see no reason why we should split hairs over the two terms. The main difference seems to be on whether the end of the stick has some sort of support or tip (usually a rubber flat tip) for better stability, in which case it counts as a cane, but I don't think we need that distinction here. At a glance in the first few pages I see several walking sticks with rubber tips without the cane tag in our gallery, so it doesn't look like people care about the distinction. If we want to distinguish them then cane at a minimum should still imply walking stick, because keeping them separate is not going to work for us. But I don't think anyone cares to put in the effort to keep this distinction.
There's also trekking_pole, because of course there is. I don't care which one we decide to go for as the main tag, so long as they're merged. Speaking of which, should this tag also imply cane? For the sake of our sanity I don't think the two should be mutually exclusive.
As a side note, perhaps having "cane" as the main tag if they're merged will discourage people from tagging random sticks as walking sticks.
Makes no difference to me if we use trekking or hiking, I would've used the former if I knew we already had a tag for it. Not entirely keen on implying it to cane, but I wouldn't argue about it.
If the first BUR is looking to be approved, what should we do with the posts that really are just ordinary sticks being used for walking support?
