There is not really demand for significant dates in history. There is also no demand for letters and hyphens mixed in with numbers, and not much of a demand for .eu. If you want to get into numerics you have to use decent patterns that go out to around 7 - 8 digits. The Chinese find the number 8 lucky, and the number 4 bad luck. I would say to find some that are 6 digits or less, but they're all gone unless you buy them at auction. For example I just got this (hand reg'd) yesterday with the #8 - 07888887.com.
