To blog or not to blog?

When I first set this website up I had to decide what elements to include that people might be interested in.  I am primarily a musician so I didn't want to waste hours of time sat in front of a computer creating stuff that nobody would look at, instead I should be practising?!  Anyway, scroll forward a year and I'm looking for new ways to update the site again so I thought I might start a blog.  I'm not quite sure yet what I'll blog about or if anybody will be interested in my ramblings but I guess we'll find out soon enough!
