Thanks for this, Mr Jones. Very useful to hear your experiences.
I tend to mostly reply to relevant girls' posts on CL, but again it's 'long game'-type stuff. So many posts get deleted that you reply, you reply and then... boom, their post is down, and they can no longer write back. The trick is to take the conversation to another medium asap. I've also had lots of aborted meetings, including with one incredibly hot - and, I'm pretty certain, real - girl on the day itself, most likely due to an 11th-hour fit of nerves or conscience. But when they work out they are wonderful, for all the reasons you and others have said - the authenticity, essentially.
