Here's a fascinating page which talks about domain names. I know--probably boring stuff to most people. But to me, with about 20 names registered with Network Solutions (3 for church, 5 personal, 14 for work), it's pretty fascinating. For instance:

• There are 676 possible two-letter sequences ending in .com, and all are taken. So are all 17,576 of the three-letter combinations. The United Brethren domain is a two-letter domain (ub.org), but with the .org extension. However, we're still pretty lucky to have registered it early.
• Of the 467,000 four-letter domain possibilities, nearly 98,000 are still available. For now. The writer says, "Choose one, and then manufacture a ridiculous backronym to explain it." Like 7RG8.com, or U3JZ.com.
• The average domain name is 11 letters long.
• The maximum-allowed length is 63 characters. There are 538 domains of that length, including one with 63 Zs. followed by .com.
• The US Census Bureau lists 1219 male names, and all of them are registered. But not all of the 2841 female names are registered. All of the top 10,000 family names are registered.
