(Merriam-Webster)

There's something special about the pixel. It's small, almost inconsequential, in fact, most people are flat out unaware of its existence. But it's an integral part of everything that surrounds us, and each one is as important as his neighbour. You don't believe me? Ever have one of the little buggers burn out on your computer screen? It's all you see! Who knew that one insignificant little black dot could ruin your day. Now, think of the opposite. One little dot, when joined by thousands of other little dots can show you the entire world and all its beauty. That's hardly insignificant. Thoughts and photographs can be such little dots. In this vast blogosphere, one man's words and pictures are one in a million. But each one is as important as its neighbour. Insignificant? You be the judge.
