This isn't exactly online dating. You've come across this girl (or guy) through a mutual interest and you have some things in common. So you've exchanged a couple emails. You want to get to know this person. Would you propose coffee?

definitely, id ask him to get a coffee at a local cafe or if he would like to join me on a day out wandering around town. something casual and public where we have distractions if it gets awkward1
