‘Web 2.0’ – by Marketing Cliché

A way of thought, rather than a technology:• ‘The world has changed’ (get with it)• ‘Loosen up’ (you can’t control)• ‘Open up’ (you can’t stay closed)• ‘Be accessible’ (not just web-browsers)• ‘Involve’ (get users on the inside)• ‘Mutate’ (continuous improvement’ / ‘gamma’;

or is that just an excuse for ‘permanent beta’?)

‘Syndication’

• Originally, a ‘syndicate’ was a group of investors, cf. a joint venture

• More recently, a means of distribution esp. of media material e.g. sports photos, cartoons, and opinions by commentators

• In this context, arrangements by which a party that originates content (a) licenses others to utilise it, and(b) facilitates dissemination of copies of it, and of metadata about it

‘Advertising Syndication’

• Overture (1998)• Google AdWords (2000)

• From ‘Pay-per-ad’ (per insert/appearance)• To 'Pay-per-click’ (per click on an ad):

• Advertisers use metadata (‘keywords’)to indicate what the ad is about

• They do pay to use a keyword• They don’t pay for an ad display• They do pay when someone clicks on it

Social Media’s Business Model• 'There must be a way to monetise this somehow'• 'You will find something interesting here'

is a self-fulfilling prophecy, because people can be enticed to contribute 'something interesting'

• Contributors, and the people who come after them, can be enticed to click on targeted advertisements

• Targeting is based on:• profile-data that users supply about themselves• content that they have donated• their online behaviour while using the service• their online behaviour more generally• data that other people contribute about the user

2. Privacy-Abusive Service-Provider Rights

Avoidance of Consumer Protection and Privacy Laws

• Location of storage and processing in data havens

• Location of contract-jurisdiction distant from users

• Ignoring of regulatory and oversight agencies• Intransigence, and negotiation of mere

nuisance-value fines and nominal undertakings

3 Privacy-Abusive Functionality, User Interfaces

Privacy-Related Settings• Non-conservative default settings• Inadequate granularity• Failure to group into Profiles• Complex and unhelpful user interfaces• Changes to the effects of settings, without advance

notice, without any notice and/or without consent'Real Names' Policies• Denial of multiple identities• Denial of anonymity• Denial of pseudonymity• Enforced publication of 'real name', profile data

4. Privacy-Abusive Data Exploitation

Exposure of Data about Other People• Upload of users' address-books, including:

• Their contact-points• Comments about them• By implication, their social networks

• Exploitation of non-users' interactions with users

• Disclosure of non-users' social networks

Location – from Added-Extra to Intrinsic

• Physical Address / Geo-Location• Knowledge of the cell that a mobile-phone is in,

is intrinsic to the service’s operation• More precise geo-location is increasingly feasible• Location is becoming readily available to the device• Location is being acquired by service-providers

• Location-based services can be valuable to users• A primary use is in consumer marketing• For most current-round SMS, location is an extra• For the coming round, Geo-Location is

intrinsic• Privacy sensitivity about Social Media is
