Years ago chain letters were sent by mail. Then there came chain e-mails. Last year I was tagged by a fellow blogger and asked to tag three more bloggers. It was the same idea as a chain letter/e-mail. Now vloggers are tagging other vloggers on YouTube. YouTuber, nerimon (see video below), unleashed this upon YouTubers in his vlog on December 21, 2007.

Each vlogger who is tagged is asked to reveal 5 facts about herself/himself and then name 5 vloggers to continue the tag chain. He states that he thinks it would be a good way to learn more about fellow YoutTubers on the site and that he hopes that the chain will keep going.
