Yes you are right. Those are very important generalist marketplaces and I would add at least Kijiji brand (PArt of Ebay) to them.

Let’s keep in mind that there is severe downturn in the US economy. However, I’d say that NY Times as well as the other newspapers suffer long term migration of recruitment, real estate and automobile classifieds to online channels. This is permanent change and it effects dramatically profit margins and revenue split of the newspaper industry. It doesn’t necessarily kill papers as somewhere is prognosed, but moves them to a new kind of position.
