I've got a cool idea for the bot but it may be hard to implement. What if it could handle messages in different languages? Like, if someone sends a message in Spanish, the bot could use something like Google Translate to turn it into English and reply. This way, people from all over the world could enjoy using it and chat together.
I could see people needing to vote the bot to gain access to like maybe 3 days of translations and with it, it would give the bot a boost on its page. People can also see it as a premier solution for overcoming language barriers which in tern will bring more people.
