Great suggestion and something we’re thinking about!
We agree and would love to see how many votes this gets.
Tags are so powerful. Not even the great Google has implemented so you guys are ahead of the game! With the ability to search by other's tags you will win the internet!
It's good you agree and I'm sure seeing how many votes this can get may be fun for you guys but the fact is that many people don't know how to search for this problem and will rarely end up at a feature request page, let alone know something like this exists.
Google Photos has a couple of great features that we wish you would add like map view and easier shared albums with shared interactivity but you guys have such a better product in my opinion. The ability to have tags from others in a shared album be actually searchable really seems to be such a logical feature that it's crazy it wasn't a part of the original implementation. If there is worry about seeing everyone else's tags in your own list then maybe have the option to include them or not when searching so you can still keep your tags as your own if necessary and not be cluttered by other peoples logic for naming. Giving us the choice would be great.
I've played with all the main file/photo sharing platforms and I think yours is the best and with this last focus on sharing (pretty important in today's social climate) it will be crowned king.
Wanted to provide an update: there are no specifics we can share about this request, but I will share with our team who is thinking through the next set of photo investments so this can influence their planning process. Thank you.
Seems the other comments already sum up the frustration of adding comments and captions and not having them be visible. Why have online and shared albums and then keep everything private and singular? Very odd strategy in a world dominated by social sharing!
