Hey, I'm having issues with the app and tags.

When entering three tags the last one is missed, unless I press space again but then I get a page with an application error page. Looks like your url mapping is broken as it sends me to /stumble/tag1/tag2,tag3 not /stumble/tag1/tag2/tag3.

I went to your app because I am always using Pinboard to find related interesting things on the web or my network to see what my peers are saving.
