Yes, is there any sites you would like to see there first?

I've started with Google Calendar, then Twitter, then Reddit and now HackerNews. HackerNews so far is the best dataset to start with. Reddit integration is half done, but still not sure on subreddits because there are too many of them.

I was thinking about Reddit - because it's so big that I never find enough motivation to browse it. Your interface is much more pleasant and encouraging so I'll be looking forward to try Storyline with Reddit. Thanks!
