How does technology facilitate the creation of a culture?

Technology helps create a culture because everyone who uses that technology has it in common. Such technology has its own jargon, and everyone who shares that jargon also has that in common and are more likely to be able to relate to one another.

The type of technology is a factor here as well. If it is communication technology, then it can help people who are already similar in certain ways to find each other and connect with them.
