Creating "unlisted" entry I'm trying to figure out the best way to create an entry that is live but "unlisted". I know wordpress has the option, and the same thing you can do when uploading videos to youtube.

What's the best way to have a post be live but not included into the regular posts returned when listing items?
If you create a Lightswitch field and add it to the section's field layout (let's call it unlisted), then you can query for live entries that have unlisted not checked with:

{% set entries = craft.entries.section('sectionHandle').unlisted('not 1').find() %}

{% for entry in entries %}
    ...
{% endfor %}
