Great! Neat-o!
One suggestion: Separate the producer into a separate, totally encapsulated
daemon which just sits there running 24x7 and slurps new articles whenever
they appear and spools them into some directory on the local drive. That way,
it can run while you sleep, even if you've exited the main user interface
program. Write that first, and get it working 100%, and it won't ever need
to change. Then allow (via API) any number of consumers to read, filter, and
display the articles. That way, you can fire up multiple filter/viewer combos,
either as separate processes or separate threads within a single process. And
if you shut down the last viewer, the spooler dameon continues to run in the
background so that when you return, all of the stuff is already fetched.
