I don't think there's really a point in making it go viral. That already happened last December, and basically everyone has heard about it. It's very likely that those who were even remotely interested has already entered, and maybe even left the market. It's even a pop culture reference now. That's not going to happen a second time unless it has something new to offer.
Is rapid adoption that necessary?
It doesn't necessarily have to be rapid, but it's for sure going to be welcome. Either way, Bitcoin is still a work in progress, so we probably shouldn't stress about its usage yet. If it turns out to be as good as advertised, adoption should follow naturally. For now, spending and supporting the ecosystem is the best we can do to help it.
