Advice: In emails and blogs a URL should link directly to the source. If the URL is long take advantage of tinyurl.com to shorten the URL.
Why: If you are trying to make a point or reference an article then don’t just link to the NYT but to the article you are citing directly. This can make for a long URL. If the source has a long url it can get broken up in the text leaving the recipient the task of copying and pasting it back together to get to the page. Tinyurl.com turns long URL’s into short ones that fit better in text.
