Scrawl is a dirt-simple blog product for Plone. It copies the News Item content type to create a Blog Entry (with a slightly tweaked view template) and adds an alternative view to Collections (blog_view). Note that blog_view shows either the description of each contained blog entry (if it exists) or the entire body. It's up to the user to limit those results in an intelligent way so that page loads doesn't take too long.
Scrawl works in Plone 3.x and 4.x (up to and including 4.3.4).
Simply add Products.Scrawl to your eggs list and rerun buildout.
Go to Site Setup page in Plone and click on Add-ons.
There is a basic migrator available for Quills -> Scrawl. Read the docstring in Products.Scrawl.Extensions.migrate_entries for more details. YMMV.
Original development by Groundwire (formlery ONE/Northwest).
Thanks to FamFamFam for the blog entry icon, which is part of the Silk set.
