I am on twitter, and if you want to discuss anything relating to this blog in a public forum, that would be the most appropriate location. As you may have noticed, there are no comments enabled in the blog. Partly this is because I'm using a static site generator, and I can't be bothered to set up Disqus or similar, partly because I'm not expecting a great deal of comment. Still if my twitter explodes (but in a good way), I may reconsider.
I'm on Facebook too, but I only tend to accept friend requests if I've actually met the person involved. Call me old-fashioned, over-literal and pedantic when it comes to the term ‘friend’.
I am also on skype, with the handle iaruffell – mainly for work purposes.
