I geotag my photos using a separate GPS Logger gadget and computer software to merge the location data into the photo EXIF. I use a DSLR, not a "smart" phone. I don't post (much) to Social Media pages but put my images on Flickr (with geotags). Also, I do not use geotag information from someone else's photo as a guide for finding places to take pictures--I take pictures of where I am when traveling as the mood strikes. I generally have no idea of what anyone else has photographed in that area. And I have a hard time imagining that many vacationers peruse geotag data and deliberately go to those exact coordinates just to take a picture--if they are doing that, they really need to get a life.

Regarding eliminating the geotag data when sharing photos, many of the upload tools have options/features for doing exactly that. JASC Paint Shop Pro did it automatically and there was no way to keep it from doing it, so I migrated to Adobe Lightroom, which has the feature (a default) but can be turned off (which I do). I understand that the Corel version of PSP now enables turning off the option to delete the geotag information, though.

The only times I would want to disable moving the geotag with a photo would be if leaving it in place would jeopardize some personal privacy issue: a photo of a child at home, photos of valuables, guns, etc. where they are located, etc. Having the GPS data in such photos would make theft or assault much easier and would be best deleted.

I don't think the "problem" of too many tourists flocking to a popular photo location is generated by people like me having geotagged photos of those places. I also don't agree that I should stop putting that information out there to try to alleviate that problem.
