result: rss feed merging results from all queries

1. the elmcity service operates on twitter as @elmcity_azure

2. the curator for the westborough, ma, hub operates as @westborough

3. if the elmcity sees twitter=@NAME in a hub’s metadata, it follows @NAME

4. because @elmcity_azure follows @westborough, @westborough can send a direct message to @elmcity_azure

5. if @westborough just added a feed and wants @elmcity_azure to aggregate now, instead of waiting 8 hours, he can send the start message:

the elmcity project did not have to build or buy software or services to:

enable curators to create and edit hub metadata

enable curators to create and edit a feed registry

notify everyone when key project events happen:

- a curator finds and adds a new icalendar feed- the project manager issues a status update- the project manager writes an article about the project- any item tagged with the subproject icalvalid is posted to delicious or twitter or wordpress

enable curators to categorize (tag) feeds

enable curators to specify default links for feeds

enable curators to assign or revoke trust on a per-feed basis

receive authenticated messages from curators

To reading, writing, and arithmetic, we should add computational thinking to every child’s analytical ability.

It is a universally applicable attitude and skill.
