A colleague asked me this this morning, and although there are quite a few UL people a-tweeting, not many of my KBS colleagues are at it. I told him I'd write him a blog post in exchange for him leaving a comment (he asked me what comments were).
So this post is a sort of learning by doing post for one chap in particular, and maybe might help others in figuring out the twitter. Thankfully there's a nice video to help us all get smarterer:
