Show HN: Cobook, the smart address book

Congrats, great to see this in the App Store. Notice though if you are a beta user of Cobook, you need to delete the beta before you can install it from the Mac App Store.

Logo and site design looked pretty sweet, but didn't want to sit through a video so I hit back. Weak landing page since I left with no idea how this works.

Actually we did an extended A/B testing on this and video only version outperformed the one with text and illustrations.

A/B testing is not necessarily a binary thing, you could use it for prioritization too. You could still display the video on the landing page (= default), with a small, tiny, barely visible button/text that directs the curious user to the page with text and illustrations.

Video and the app look fantastic though, best of luck. I almost never watch a video too, but I watched it this time and liked it a lot.

During app install:

"Cobook automatically synchronises contacts with OSX standard Address Book. Updates in Cobook are instantly reflected in OSX Address Book and vice versa.

Privacy is important. Cobook stores all your data and settings locally on your computer. Only you have access to your contact data."

Thank you. This really should be on the website somewhere too. The only reason I downloaded your app at all was that your last blog post mentioned that you don't collect data. I'm usually very cautious about things that involve messing with my email, contacts or calendars.

Also, I didn't watch the video so felt as though I was forced to go hunting for more info on the site. You say you A/B tested but did you also test a version with video and text on the front page? I'd be surprised if video alone performed better.

Edit: Now watched the video (having dug out my headphones so I don't disturb co-workers). It actually does do a good job of describing the problem and how the product works. Looking forward to trying this out.
