I am looking at launching very soon - next week. It will be a brand new platform so it might not be something you're look for. Can I DM/email you when I launch? Even if you end up not using it, I'd appreciate any feedback I can get.
I am working on something that could compliment this. If you're interested in working with someone, as a cofounder, in this space please contact me on the email in my profile.
If you spend some time traveling the world you will see not everything is the same. From Tel Aviv to Mumbai to New Zealand. They're all different with different people, cultures, coffee shops, foods, languages, history, etc, etc.
I am actually developing a web app that highlights these differences. Each week a different country is highlighted and users can post content about that country.
