An article in yesterday’s New York Times looks at some of the criticisms that Facebook has been facing as the novelty of the site has worn off for some and the pressures as a public company to make money have increased:

• the feed should offer more relevant content
• feed content should engage users more deeply (so they stick around and notice ads more)
• the sponsored stories in the News Feed have turned some users off
• more people are taking breaks from Facebook for various reasons
• teens are no longer flocking to the site and turning instead to Instagram, a company Facebook acquired last year
• the promoted posts that companies and individuals pay for have raised questions about how the algorithm is being secretly adjusted in ways that suppress the posts from your friends
• some feel like there’s too much junk in their News Feed and content that they really care about is being hidden or drowned out in content that’s not relevant or interesting to you
