Digital Publishing Workflow Management

I have a serious problem with how I find, attend to, curate, add to, and finally, publish information. Here’s my basic flow today:

I use Facebook, Twitter, RSS, email and web-browsing to find interesting items.

Then I use Google Reader Shared Items, Twitter Starred Items, Facebook Likes, Instapaper, Delicious, and Tumblr Likes to store the things that get my attention.

Finally I publish a subset of those to 2 Tumblr Blogs, Twitter, Facebook, and this blog to capture ideas and share what I find interesting

I’d like to review everything from a certain time period and collect the best ones for sending in an email (and I’d love a tool to help judge which in that mountain of sources got the most reaction from the world).

This is broken I need help in fixing this, and it could be helped by a very simple workflow tool.

I’d also like whatever tools I use to collect items that get my attention to add a data layer that I can use to make interesting connections later (example: tags in delicious). Taxonomies and codification is good because it helps me understand the information better, however, I need to understand how I’m going to reference that taxonomy later if I’m expected to keep it up manually.

How many people have this problem? Is there a niche market product for this serving bloggers/journalists/intellectuals here? What would a well-built “publishing workflow management for teams of 1″ look like?

Anyone wanna ruminate on this one with me? I have several ideas.
