As someone who likes to share data sets via IA, their hiding of the plain list of originally uploaded files behind a non-colored link that only gets highlighted on mouse over made me furious many times. I don't want to have to combine a simple "download my data there" with "then move the mouse there and see how it is actually a link and oh by the way the actual files I meant to link you to are available if you click that".

I totally understand their motivation and I think it is great to present the potentially popular parts of the archives to the public in an "experience". But it worsened my user experience and motivation as a contributor(!).
