Here are a few paragraphs from the NYT article:
"Former bloggers said they were too busy to write lengthy posts and were uninspired by a lack of readers. Others said they had no interest in creating a blog because social networking did a good enough job keeping them in touch with friends and family.
"Blogging started its rapid ascension about 10 years ago as services like Blogger and LiveJournal became popular. So many people began blogging — to share dieting stories, rant about politics and celebrate their love of cats — that Merriam-Webster declared “blog” the word of the year in 2004.
"Defining a blog is difficult, but most people think it is a Web site on which people publish periodic entries in reverse chronological order and allow readers to leave comments.
"Yet for many Internet users, blogging is defined more by a personal and opinionated writing style. A number of news and commentary sites started as blogs before growing into mini-media empires, like The Huffington Post or Silicon Alley Insider, that are virtually indistinguishable from more traditional news sources."
"Blogs went largely unchallenged until Facebook reshaped consumer behavior with its all-purpose hub for posting everything social. Twitter, which allows messages of no longer than 140 characters, also contributed to the upheaval.
"No longer did Internet users need a blog to connect with the world. They could instead post quick updates to complain about the weather, link to articles that infuriated them, comment on news events, share photos or promote some cause — all the things a blog was intended to do.
"Indeed, small talk shifted in large part to social networking, said Elisa Camahort Page, co-founder of BlogHer, a women’s blog network. Still, blogs remain a home of more meaty discussions, she said.
“If you’re looking for substantive conversation, you turn to blogs,” Ms. Camahort Page said. “You aren’t going to find it on Facebook, and you aren’t going to find it in 140 characters on Twitter.”
I have to say that I still love to blog. Largely because I love to write. But not a lot of folks read my blog unless I connect a post to Facebook. Then there's a momentary flurry. So there you are. Folks don't have time to write on blogs or think they don't and more folks don't have time to read blogs. A tweet is short and sweet.
