Pros
-Easy to use
-Fun to play with

Cons
-Website design looks slightly boring (in my opinion)
-Not a lot of users/emojis yet
-Many existing emojis seem to be Asian symbols, which may not be attractive to other people

As you stated, the website is new though and can still change a lot. Once it gains in popularity, gets a nicer design and more people from different countries start adding emojis, I believe this platform could be very neat. All in all, nice hunt, @ryacha21 !
