Fans of the European Parliament Facebook page have been extremely active lately. It’s not always obvious to us why this happens on this or that subject, but of course we are delighted to see it when it does so. In particular, we have seen a very lively discussion on EU enlargement, which really seems to have got people going. The quality of the posts is striking. There were 196 comments at the time of writing. (Of course, you need to be a fan to see it all, so, if you’re not, it’s a good chance to join in…)
