The Portland Tribune is a twice-weekly free paper, printed and distributed on Tuesdays and Fridays. It is owned by Robert Pamplin, who also owns KPAM (AM 860) and the Community Newspapers Group. The news initially was only to be about Portland, but now it also covers the suburbs as well (which is good, as the editorial offices are now in the suburbs). Issues tend to be about 16-32 pages long. The news consists of a long front page story, and a number of shorter pieces.
Both in print and online, they have their content divided into news, opinion, features, sports, sustainable life and classifieds.
The front page online is updated between print editions. They do not appear to have RSS feeds.
While some issues have a decided conservative slant (alternative and public transportation, public spending, small business), and editorial feature work generally reads like PR pieces, they can pull a real surprise out of their hats every now and again.
They have all of their content online, and while they have recently switched content management systems (and broken all of their old URLs), they have a well-oiled search engine to find material. They don't appear to take material down, which I appreciate. (Now, if they had some sort of redirection rather than their ugly 404 message).
