Stay.com: Create your personalized city guide.      
[tools / technology / travel / culture]

If you’re like me, you crowd-source restaurant recommendations whenever you’re traveling. It’s the best way to see cities you aren’t familiar with because you’re essentially guaranteed to have at least one amazing experience. (It’s how I ended up at Tickets in Barcelona over the weekend.) Stay.com lets you curate suggestions (from strangers or travel mates) into a customized guide book. Which is accessible, even without an internet connection. Awesome.
