We tend to hangout with someone that we found interesting to talk to especially when the subject is related to what we love the most. Highly unlikely we want to spend our time with someone that is cold..boring. Same goes to the person that you wish to impress.

We may apply the same concept online. Just find out the person's interest... Let say, he love martial arts and have active conversation in few groups. Join the groups, and start talking the same language.. until he notice that you're the interesting one to talk to. You may have high chances to meet him for a coffee. Based on my experience, it works like magic! the great part is.. we became good friends. Cheers
