I believe you can tell more about a person with a 10 minute face-to-face conversation than weeks of online messaging. At it's core, we are on this site to meet interesting people for either friendship or the possibility of new love.
If you are interested in actually having a conversation over a cup of coffee, tea, beer, etc, I'm interested in sitting across the table from you. Worst case, we find we are not compatible without wasting too much time. Best case, we make a new friend or possibly more.
