Added user scenarios and some notes.
=== User Scenarios ===
==== As a front-end developer, I need my program to be "push" notified of updates from the server and other data sources, so that the client can efficiently react to the most up-to-date information. ====
==== As a front-end developer, I need to be able to specifiy sub-sets of information and be notified when these sub-sets change so that parts of the interface can react to the data that interests them. ====
''There are a few ways to do this. Event channels is one. Filtering is another. If you think about it, event channels are really a domain-specific-language around querying change notifications. I prefer a filtering approach because predicate functions are more flexible than DSLs if we still should want an event channel DSL, we could create one on top of predicate functions.'' -[[Gbrander]]
==== As a front-end developer, I need to transform and reformat data coming from the server for display on the client-side. I need this transformed data to be "live". It should be updated when the original data is updated. ====
