How long is 5 years in blog years?

I just realized that I have been writing this blog for just over 5 years.   At one of the sessions at yesterday's Dig conference, a speaker referred to a game that came out in 2004 as if it was from the stone age.  Amusing - but illustrates how quickly things are changing.   If anyone doubts that, take a look at this Socialnomics video that I referred to a few weeks ago.
