I've been trying out Omegle recently and bar trolls it's good fun. Here's something I want to spread as much as possible though:

When you start a conversation, after saying hi you should offer your stranger a coffee ... if they reply with either "yes but make it strong, i want to see that spoon stand up" or "and some carrot cake too?" you know you've got someone who's been affected by me or someone i talked to at some point

And of course, I'll know that too if you're talking to me!

Also, [link] is a very similar principle (apparently around before, but not as nice layout as Omegle I dont think) and in my first (and only, so far) chat on there I found a fellow skydiver. Whatre the chances?
