First of all, Triptogether is quite new, so it's less crowded compared to other similar sites.
It has many interesting features but the best part is that all the members are verified and they really exist!
I didn't believe it, so I browsed most of the profiles and I realized it's true! I met with Monica in Poland, she is my new friend from Triptogether and she does exist!
It also looks very fresh... so far, no negative points
