Just looked again at the page layout, and actually I quite like it. I think it clearly shows the application name together with how it uses Akonadi, which makes it very clear, in my opinion. I don't know how to get a full list of apps using Akonadi, and even more important, I don't know how to maintain it - is there some resource where we can find this info?
Don't worry about the markup issue - we can help with that if needed. I see that it is using the recently added template to get the clickable links and I think the result is good.
You will usually find me, Claus_chr and neverendingo on #kde-www - and pipesmoker, though not around quite as much, also is able to help. That's probably better than using the mailing list, although the list kde-www would also find us,
