Big improvement in usability, I would say. A couple observations:
Under the “people” tab, Sarah Lane Ritchie’s photo is not centered properly in the circle and it is not aesthetically optimal.
Under “about us” / “advisory” council, it looks like Claude Alexander’s first name is Bishop. Nobody else has a title, though presumably several are Reverend or Doctor. So this looks weird to me. Does he want to be listed like that?
Nice putting the annual reports on the giving page.
If I were coming for the first time, I would look at the tab “people” first because of its position. But I think the “topics” tab would probably be a more helpful place for most people to start, as it gives a very good overview of the content of the website. If I were designing things, I would flip the two tabs.
So, are you doing away with the four separate blogs and just having generic BioLogos published articles? You need to do something about the fact that all of your articles are still linked to the separately named blogs, (President’s Notebook, Evolving Evangelical, etc.), but now those links take you to a page that’s empty of content. http://biologos.org/blogs/ted-davis-reading-the-book-of-nature
