The venerable NYT has discovered that — shock, horror! — many people who start a blog don’t keep at it. Whatever next?

Many people start blogs with lofty aspirations — to build an audience and leave their day job, to land a book deal, or simply to share their genius with the world. Getting started is easy, since all it takes to maintain a blog is a little time and inspiration. So why do blogs have a higher failure rate than restaurants?

According to a 2008 survey by Technorati, which runs a search engine for blogs, only 7.4 million out of the 133 million blogs the company tracks had been updated in the past 120 days. That translates to 95 percent of blogs being essentially abandoned, left to lie fallow on the Web, where they become public remnants of a dream — or at least an ambition — unfulfilled.

Judging from conversations with retired bloggers, many of the orphans were cast aside by people who had assumed that once they started blogging, the world would beat a path to their digital door.

“I was always hoping more people would read it, and it would get a lot of comments,” Mrs. Nichols said recently by telephone, sounding a little betrayed. “Every once in a while I would see this thing on TV about some mommy blogger making $4,000 a month, and thought, ‘I would like that.’ ”

Not all fallow blogs die from lack of reader interest. Some bloggers find themselves too busy — what with, say, homework and swim practice, or perhaps even housework and parenting. Others graduate to more immediate formats, like Twitter and Facebook. And a few — gasp — actually decide to reclaim some smidgen of personal privacy.
