This is interesting. I found it on Paul Krugman's blog:
Can I still access NYTimes.com articles through Facebook, Twitter, search engines or my blog?
Yes. We encourage links from Facebook, Twitter, search engines, blogs and social media. When you visit NYTimes.com through a link from one of these channels, that article (or video, slide show, etc.) will count toward your monthly limit of 20 free articles, but you will still be able to view it even if you’ve already read your 20 free articles.Hmmm. It sounds like posting links from the blog will still be doable. Good!
When you visit NYTimes.com by clicking links in search results, you’ll have a daily limit of 5 free articles. This limit applies to the majority of search engines.
