Question of the day: I'm curious if you have any recommendations on young, hip editors as well, possibly those specializing in the chick-lit genre?
I don't have any specific editors whose names I'd feel comfortable passing along, but the good news is that this info is pretty easy to come by. The best place to start - if you're willing to shell out $20 - is Publishers Marketplace. Type in the name of books that you like and see who edited them. Whether or not they're young and hip by definition, they probably like books like the one I'm guessing you've written. If you don't want to pay for PM (and I think it's an invaluable resource, btw), check out the acknowledgment pages of books you like: nearly every time, an author will thank their editor.
Once you have that info, feel free to google 'em. Yeah, yeah, this might sound stalkery (and it is), but you'd be amazed what you can learn from google. At the very least, you might find out what year she graduated from college, and at the very best, I dunno, maybe you'll glean some insights from her Facebook page.
But. All of that said, I do want to issue a slight warning: yes, there are probably some intangibles that you can discover to see if you'd click with an editor, but, not to be too cliche about things, you can't always judge a book by its cover. By that I mean that just because an editor isn't "young and hip," by your definition, doesn't mean that she won't kick ass as an editor or won't be interested in your chick lit book. Some young/hip editors only read highly literary works while some older-skewing ones adore the lighter fare. So I'm just saying. Sure, go google, go find the editor whom you think you'd want to hang with (and yes, this can also be important, I'm not denying that), but remember that this isn't everything.
Readers: how important is it that you and your editor are friends? That you like her/him outside of just work?
