I'm the founder and Admin of this channel. I appreciate your constant contribution to "Travel the World". But may I come up with a suggestion?
If you added some more information about the pics you post, the cards would be even more valuable - and would perhaps get more APs. Some people around do consider posting pics without any or with just little context spam.
Maybe start telling stories about those cities and places. It would also be interesting if you shot the pic, who did actually and why you picked it for your card.
