I have started implementing trackbacks on my blog.
I thought it would be a lot of work, but I was able to send and receive pings after just a few hours hacking away.
Of course, the devil is in the detail as they say and making it work just that little bit better will take a lot more time and effort.
I watched a demo of trackback usage on the movable type blogging tool and it made me realise how amateurish my own blog is behind the scenes.
More guff for my todo list I suppose.
