I'm a big fan of BufferApp as a tool for scheduling tweets and getting some good analytics on click throughs etc.  So it's lovely to see that they've made the process a whole lot easier by buying the social toolbar makers DiggDigg recently.  DiggDigg make it really easy to add a sharing bar to WordPress blogs.

I installed it this morning, so you can see what it looks like by looking at the left hand side of this post.  Well worth checking out if you have a spare minute or two.
