The end of the tabula rasa users?
Nobody uses only one service/website.
Nobody wants to waste time on content they don’t like.
Blank Slate doesn’t have to be blank.
Let’s import the history from other websites.
Whatever it is that our service does, it will always be a fraction of the online life of our user. might as well play with others.blank slate, import history = during signup (?)

Show him the possibility of importing attention profile.
User decides to add a few websites:his blog, ma.gnolia, last.fm

Non-blank slate!

microformats - Semantic Web takes too long > Tantek Çelik+Kevin Marks wanted the semantic web today, in 2005.the formats go through a process of specification involving the community, using technologies/languages already available today. easy peasy to author.
apml - is a format spec’ed by Faraday Media (chris saad). Previously, technorati had tried with Attention.xml. Didn’t survive.

Check for APML - if present, absorb.
Check for rel-tags - group set of tags and calculate an average and absorb.
Check for rel-next, rel-previous, rel-archives and for each one: goto 1.

NEVER import any detail without the explicit authoriation of the user
Allow (not impose) the user to export through an APML feed the attention generated through our service
Keep data up-to-date.(fixed periods, dynamic TTL, XMPP, etc.)
Warnings

ttl = time to live of the cache.
“So, Data Portability is not about letting your users ‘walk out’ of your service. Data Portability is about enabling, empowering and encouraging your users to bring all their data with them, to connect your data to the rest of their data ecosystem and to continue to refresh and maintain the data on an ongoing basis.”
To conclude...
