Any business Ideas for these domains?

[Machiavelli]

Last year, I received two very short .co domains, which were pre-ordered by somebody I know.

yumm .co & zuu .co

I would like to build some unique websites for them, as both are very short, memorable, and search engine friendly.

Anything can really work for them... it's almost like hulu.

I have been thinking for a while and can't think of anything clever yet, almost thinking about selling them (got a couple decent offers on them already) if I don't come up with something good.

Any ideas on what would work well on either one of those?

Yumm : A website based on choclates/cookies. A taster or preparation collection.

Zuu : How about a cartoon category.

My first views on reading the names.

Yumm is begging for something about foods or sweets.
