Ivar Ekman points out Google’s Jaiku poses a privacy risk.
Ahem. That’s the point of disclosure.
Presence: Dimensions of Disclosure Influence
- Recipient
- Data
- Social Context
- Time Value
- Licensing
And presence.
Presence is the approved radiation of your latest information.
Presence authorization is not a binary disclosure to Everyone or Nobody.
Authorization can be, must be, tailored to the recipient.
Four dimensions of influence:
1. You might base disclosure on attributes of the recipient.
- Groups they belong to (family, co-workers, people I hate),
- age (adults-only data),
- location,
- citizenship,
- security clearance,
- social proximity,
- relationship history (people you’ve talked/chatted/met with in the last year).
Jaiku and facebook share presence based on group affiliation and social connection.
2. Perhaps authorization is more closely tied to which data you share. 
Some people share their calendar. Do you share just your availability? Your location at a given time? What you’ll be doing? With whom?
3. Social context frames the authorizing decision. Perhaps you don’t share your political life at work. Or your fantasy blog with your family.
4. Time and your Sense of Now change the value of information. Do seconds matter? Minutes? Hours? Some information is better shared late. Perhaps you enjoy sharing the restaurants you visit, but not while you are there. Other information loses value quickly: minute-to-minute election day results, for example.
5. Licensing sets terms of use. Perhaps you agree not to share this data. Or to only share it under certain conditions.
The blend informs disclosure. Of what you share with whom, in each context and precisely when must inform disclosure. You should be able to share your latest blonde jokes only with your blonde friends (data and hair color of the recipient).
Presence is subscribed to, actively requested, not only available for public scraping.
Presence subscription calls for subscribers to disclose too.
So Authorization looks like Negotiation…
- “I want to subscribe to information about you.”
“Are you representing a human?”
“Yes, here are my credentials.”
“Ah, looks like you are on my client’s friend list. Here’s a list of feeds you’re eligible for.”
“Jokes! Cool. Yes, I would like to see your joke stream.”
“I need more information. Have you ever tripped over a wireless phone?”
“Yes, I am a blonde.”
“Great. You agree to only share these with other blondes?
“On my blonde honor.”
“You should be able to see the blonde jokes stream now.”
Since Dave Winer and Netscape first promoted RSS in 1997, syndication meant being public, sharing your content with Google.
