How will you know what I like?
Hey I'm one of the creators of Delight. We're using Twitter as a starting point. We hope to work out what makes you tick, but ultimately that will only come from a conversation with you - thus why we've chosen to individually curate and pick content for all our users by hand. If you pass us on any more info by clicking on "Tell us more", we'll use that too.
Have you considered using hunch.com to help with this?
