I have a little Lotus Notes agent that reminds me of birthdays and other important events. It's just informed me that my first blog post was 12 years ago on 26 March 2002!
There was no Twitter then - Twitter did not come along until 2006. Nor was there Facebook - Facebook was not founded until 2004. And LinkedIn started up in 2003.
And I have just checked, my first Knowledge Letter was published on 30 May 2000. I have published it every month for 165 months - that's almost 14 years. One day I will stop but not just yet!
I always thought it was the age my children that dated me - now I am not so sure :-)
It's amazing how social media has bloomed in the last 10 years.
