Why blog?

Following on from yesterday's post where I posed the question, "why create a blog?"... Last night I was watching Rick Stein's Far Easter Odyssey and Rick was talking about why travel writers write, and why journalists travel the world recording their experiences. He said it's because it's therapeutic and a way to escape the realities of life. I thought that applies perfectly to why I feel the need to create this blog. It's like a diary (albeit a very public diary!).
