Where is Obama?

It doesn't make much sense to make the President's whereabouts specifically well known since they are already quite well known.

If you really wanted to engage the folks involved in domestic data collection with a visceral sense of "a stranger is watching me" creepiness, you could — and I don't think this is a good idea — launch a site like "Who Is Everyone Who Has Interacted With NSA Director Keith Alexander?".

Imagine if someone used press reports to find names of people who have been seen publicly with Alexander. Then suppose that they built a dossier for each person containing detailed information about their name, date & time & nature of their documented interactions with Alexander, current address, most commonly used usernames on common public Web sites, links to any online "profiles" where available, educational background, property records, voting history, criminal record, all online postings, current and historical location information as inferred from Tweets or other sources, and any connections to any other "people of interest". Imagine seeing all this dossier-style information availably publicly with a quick Web search — it would be very creepy.

(This is not really that different from what the folks at cryptome.org do.)

I do not think that this would be a very good idea to do because I don't think the possible contributions to discourse (slim if any) would be more valuable than the possible harm to the folks in question.

On days when the government isn't shut down, they post his full schedule to http://www.whitehouse.gov/schedule =P.

You can usually tell where he will be because they have to establish security beforehand, such as using TFRs in the US to restrict flights in the area, and of course they announce it a lot. That being said, only the higher ups know his itinerary for certain and know how he will arrive, etc. Just like GWB "disappeared" and then arrived in Iraq, they move around quite secretly. For good reasons, people really do want to kill the US President. So I would think this is data recorded after he has arrived.

What would be more impactful would be "What Gen. Alexander has for breakfast". Not that would get their attention.

Lame, poorly executed, and missing the point entirely.

I wonder how quick this would run afoul of the Secret Service, let alone there are probably laws they can twist to intimidate if not detail people, shut down sites, and do random searches of associated computers.

I seriously doubt based on his history he is going to give a damn. Considering how insular DC is he would most likely have support on both sides of the aisle if this ever took off.

The linked to site is pretty clearly a political propaganda operation. From their choice of "stories" and very careful chosen wording, ala Fox "News". Should be beneath the HN community.
