How to create a simple Activity Stream Weekly Digest using CCK and Views

I was researching for an easy method to publish as a single post my latest {month|week|day} activities on twitter aggregated by Activity Stream. This is how I did it:

• Create a view that list the activity stream items published in the last week;
• Create a new content type (ex: activitystreamdigest), add a node-reference cck field with unlimited values, checkboxes as widget type and the precedent view as nodes that can be referenced;
• Update your frontpage view to include this new type of content (or promote them to frontpage, as you use to deal with your contents)

Now, everytime I want to create an Activity Stream digest, I go for Create Content -> Activity Stream Digest, I select the items I want in my digest (throwing away unuseful tweets) and publish.
