It's a bit surprising that there aren't that many good CMSs for node given how itd adoption is going. KeystoneJS is really cool.

Pros: really easy to get started (yeoman generator), bootstrap, jquery etc included in the box, auto-generated admin UI. Does a lot of the boring stuff for your at the start.

Cons: the content management could be better. Apparently it's this side of things is under active development, but for now its more geared to managing list of things, rather than static page content.

Worth a look in any case.
