As I've always said, this blog is written largely for me. A place to record thoughts, experiences and progress. But it's also where I keep useful links with a little comment as well: a more engaging Delicious perhaps. So here's a link, tucked under the image above, to a Roland Harwood (@rolandharwood) post on networks. My comment is to suggest that I read it again the future and if I encourage others to have a look as well that's all fine by me.
