First of all, never publish a list of names you're considering unless you already own them as domains. Frequently, somebody will learn about your intentions, then go register your target domains in order to sell them back to you for much steeper prices.

That's unethical, in my view; but it happens. Sometimes company employees or contractors (e.g. web designers) do this. So I'd be cautious even with internal communications. But definitely avoid public statements.

That said, I'm not recommending that people go out and buy each & every name candidate in advance. Obviously that would be wasteful.

It's clever embedding the "why" pun within "wise" in Whyse.Life. However, while it functions alright visually, it fails when the name is heard. Far too many ambiguities, between the creative misspelling and the novelty suffix.

CrowdSage.com is the clearest name in the list. No ambiguities or extra details to remember. The others aren't good enough for you. Whether CrowdSage.com is a good choice or not, I can't say without further research.
