One of the things which is so great about tattooing is that it attracts
interesting people from all demographics. The simple truth is that some
people feel a desire to permanently mark themselves with things that
profoundly affect their lives. I don’t know if this is some genetic
leftover that helped primitive humans hold their social fabric
together, or whether it’s an unavoidable byproduct of being both
narcissistic and sentient creatures. Either way, people get tattooed
every day with the things that define their lives — and “nerds” and
“geeks” are no different.
After all, who wouldn't want to show their lifetime loyalty to acomputer system, gadget, or game character?
