I had a chat with Alastair about this yesterday. Now that there is a detailed speaker page (i.e. each speaker has their own page that shows just their details - http://dddeastanglia.com/Speaker/Details/23), there is less impetus to have an anchor to link directly to the speaker's part of the whole list. It is still valid to put the anchors in just in case, but there is probably no need to have the list at the top of the main speakers list.
