As you chat with your new acquaintance, feel free to throw in visuals of your hobbies, travels, or any other experiences that will really bolster your conversation.
I think in general humans like to be able to see whatever it is they happen to be talking about, the same way a lot of people tend to consider themselves visual learners.
Talking to strangers is not simple, in person or online, but once you establish the communication with someone you truly like, that person ceases to be a stranger and becomes your friend.
