Instead of using new technologies to preserve for ready discovery material that might in the past never have been stored, or deleting everything as soon as possible, we can develop systems that place sensitive information beyond reach until a specified amount of time has passed or other conditions are met.

I'm interested in helping secure the PC - we need innovation here. It's not just hug your PC, hate the iPhone. In fact I don't even hate the iPhone; I think it's really cool. I just don't want it to be the center of the ecosystem along with the Web 2.0 apps.

The last refuge of privacy cannot be placed solely in law or technology. It must repose in both, and a thoughtful combination of the two can help us thread a path between having all our secrets trivially discoverable and preserving nothing for our later selves for fear of that discovery.

Attacks on Internet sites and infrastructure, and the compromise of secure information, pose a particularly tricky problem because it is usually impossible to trace an attack back to its instigator.

I don't know how much thought is behind it, but it seems to me highly effective the way that Facebook will let somebody tag a photo with a friend's name, then others who are a friend of that friend can perhaps immediately see the photo, and the friend, in the meantime, has a chance to wander back and un-tag it.

I'm interested in harnessing the good will and distributed power of people, including novices.

Facebook draws from the public and public-interest sphere, a simultaneously bold and modest step towards acknowledging that our new networked technologies deeply affect our lives in ways not always captured or best shaped by the typical template of consumer and seller.

Thanks to iCloud and other services, the choice of a phone or tablet today may lock a consumer into a branded silo, making it hard for him or her to do what Apple long importuned potential customers to do: switch.

With the rise of software patents, engineers coding new stuff - whether within a large software company or as kids writing smartphone apps - are exposed to a claim that somewhere a prior patent is being infringed.

People may be due the benefits of a democratic electoral process. But in the United States, content curators appropriately have a First Amendment right to present their content as they see fit.

Despite outsiders being invited to write software, the iPhone thus remains tightly tethered to its vendor - the way that the Kindle is controlled by Amazon.

Being closed to outsiders made the iPhone reliable and predictable.
