I wouldn't recommend this approach. A relationship is built out of time spent physically present with a person, trying to hack this by building a relationship with less time spent before marriage, or by substituting time spent in presence that is not physical, makes for a weak bond that will likely break after a few years of marriage, particularly if one or both of you have poor social skills.

I emphasize social skills because, like Vitamin D, the hacker lifestyle leads us to be deficient in such a vital resource. We should be supplementing our lifestyle with lots of activities that force us to interact with other people in ways we're not used to. I've been going to the same bar for the last 8 years. It's often painful, I still don't really fit in, but it's been crucial for helping me develop my sense of self.

Another good place to frequent is coffee shops, but good neighborhood coffee shops are quite rare. Starbucks doesn't really do the trick, something about the atmosphere discourages the kinds of spontaneous casual community that you really need to develop social skills.
