Moe pictures and probably something translation-related sounds good too. Though the latter would be too much trouble…

Or perhaps the “something so crazy, cool and revolutionary that I haven’t thought of it yet” option, though it seems like it might be difficult……

I have an idea for you, though. It fits with the name, and could be interesting.
You know how everyone is always struggling to define moé?

Take a look here: http://bestthing.info/algorithms.html
Also, look at one of the sites itself, like thecutest.info.

Now, steal the idea, but fill the site with moemoe bishoujo instead.
Allow user submissions, but require they be approved by you before they go onto the site.

In the end, we will have the Collective’s definition of moé.

Not only is it a good idea, but it should be quite easy to implement. Just make sure people can’t get away with biasing the results in favour of their preferred heroine.

(P.S. speaking of moé, upload the full version of your Nyro~n banner picture somewhere)

Failing that, starting a danbooru backup site on that domain sounds nice too.
