Set a work and home location so that it knows when you really are out and about. Start using G+ if you don't already (eg I got a birthday alert for someone yesterday, via Now, via G+). Set some data in other google applications (Calendar, Finance, etc). All roads lead to Now. (Well, some do)
Imagine how useful intelligently feeding google reader data into Now would be... oh wait, whoops. Aside from whining about Reader being cancelled I am serious that sniffing relevant RSS feeds would be a highly useful feature to add.
I've had it for a few months on my Nexus 7. In summary its travel and shopping push notifications. I had the usual intense short lived "oh that's really cool" reaction and haven't used it since then and its had no measurable impact on my life. Kinda like my relationship with facebook and linkedin and twitter.
In the eternal wheel of IT, where nothing is ever really invented, merely recycled every couple years, this is the reincarnation of the pointcast internet screensaver app from the mid 90s. Back then the complaint was it was spammy and didn't provide real value, so after a similar intense publicity wave quieted, they dried up and blew away with the wind, until now (literally, "Now", get the pun? Yeah well bad pun; bad puns never really go away just get recycled later...)
I don't think it would be very useful to have RSS feeds in Google Now. I like Google Now because it tells me what I want to know right now, like that my flight is delayed or traffic is bad or here's how to get to that restaurant and you need to leave in 15 minutes. I don't want to know about a new article right now.
Perhaps. But the app has very little to say if you're not traveling or shopping. Personalized news would fit in with the "a push of personalized interesting stuff" model. On the other hand if its sticking to the "travel and shopping" model then I do agree news would be inappropriate.
You have cards for breaking news, and updates on stuff that you've searched Google News about (e.g. for the Boston bombing, I was getting regular updates on the situation. If you don't want to hear about it anymore, you can opt out easily.)
