A better answer would have formed a stronger connection between the topic of our conversation and your vacation. Saying you could visit the computer tech capital of the world is a weak attempt - we weren't really discussing cutting edge technology, only minor formatting tricks.
Also, a truly satisfying answer would need to demonstrate why this topic is relevant to the original discussion not simply by shared subject matter, but rather by some kind of intrinsic link - for example, if we were discussing this because you were considering taking such a vacation, that would be strong linkage and thus a legitimate answer. But simply saying there's a marginal overlap in subject matter is definitely a reach!
Personally, I suspect there is no really satisfying answer, which is why I challenged you to begin with!
no subject
