Right, I'll just round up my suggestions and those I agreed with from other comments: - In portuguese, and I imagine a lot of other languages, "mongo" is a pretty nasty word. Think "retard", only worse. - Have this linked with your reddit account so you can up/down vote. Also, then you could, by default, show pics from the user's default subreddits. You should allow an user to add/remove subreddits to get pics from,…
I'm Portuguese too, and "mongo" is not even a word, let alone a nasty one. "Mongolóide" is a nasty insult, but is not usually reduced to "mongo".
It is a very offensive shortened form of "mongolóide" where I hail from.
