Twitter is five years old and to celebrate co-founder Jack Dorsey is sharing fun facts about the sites history and growth.  For example, it took three years, two months and one day for Twitter to go from one tweet to the mind numbing one billion per week they boast now.

Another topical fact: 177 million tweets were sent in response to the earthquake and tsunami in Japan.
