Anybody out there?

My first blog. What do I say?
Usually what you say depends on who is listening. This is like a leap into the unknown. Who will read this? Friends, colleagues, aquaintences, employers? Is it making oneself vulnerable to exploitation by exposing oneself in public? Is it a marketing tool? Does one reach out to others with lifes lessons learnt or insights gained? Or is one merely being self indulgent and full of ego?
I will have to see what happens as I go along.
