The internet enables us to talk to people all around the world, about any and every topic. That's incredible! So, let's chat -- tuba, electronics, cool music, art, things of interest; the field is wide. However, don't be creepy. The internet's already way over quota for creepy people, so don't be one of them. (If you have to ask if your message is "creepy," then it probably is.)
Thanks for being cool, future internet-friend!
