Twitter — specifically Twitter's effect on the way we communicate and interact — is amazing. The sheer volume of 140-character communiques flowing across the service's wires is high enough, in fact, that you're now able to find a mention of the current time for virtually every second of the day. Chirp Clock pulls those tweets, minute by minute, and assembles them into an endless stream — not the most efficient way of telling the time, granted, but easily the most likely to have an occasional Bieber mention.
