Best new rental listing web site

[Amit M.]

so craigslist has been the stalwart, but I'm hearing of new web sites and apps that take advantage of social media, crowd sourcing, etc. specifically for apartment rental listings. Sites like zumper, lovely, etc. doesn't trulia and red fin now also list rentals?

I've been using Craigslist as a default for years, but want to plug into the latest site or app that tech oriented people are likely to use.

Any ideas which are the best/most popular? Is there a regional slant? I'm in California/Bay Area. Thanks!
