Got a big laugh Saturday night when I said this to friends, but it’s true. Blogging has become long-form writing in the advent of Twitter and Facebook. Only the truly committed do it. And only the truly committed bother reading them. In web terms, blogs have become epic novels.

I discovered this as a guest lecturer at a journalism class at Bergen Community College. When I asked if anybody blogged, one hand went up. Five or six years ago, it was a truism that only the young blogged. Now they don’t bother. They microblog. On Facebook.

The young don’t Tweet either but that doesn’t mean that Twitter isn’t the most potent social influence in recent months.

Thought — and thinking — has been compressed into 140-character chunks.

Wait until it’s crunched down further into the size of a message on a Valentine’s Day candy heart.
