[Lex Computer & Tech Group/LCTG] earth rotation

[Michael Alexander]

The article is an interesting thought-curiosity.  However, it doesn’t address the foundational question:  Why on earth [ :-) ]  should the earth start rotating faster??  
The earth’s rotation actually should be slowing down.  Why?  Because of friction from tides (on land as well as water).  Tidal friction acts as a kind of brake (think of the friction from a bicycle brake slowing a rotating bicycle wheel).  
Long-term (very long-term) earth’s rotation will slow so earth keeps the same face opposite the moon, just as, today, the moon ‘shows’ one face to the earth.

Pretty interesting story on what happens if the earth's rotation speeds up
