So, eHarmony matched me with a guy I work with - what do I do?

We work for the same company in the same city, but at different offices. I see him on occasion and we know each other’s names, but that’s about it. He’s a nice guy and I might be interested in getting to know him better, but I’m not sure how to approach this. Should I just leave it alone? Do I send a message to go ahead and break the ice to get the awkwardness out of the way? I could sure use some advice on this awkward situation.
