Does blogging have to take a lot of time?

Scott Karp posted an interesting piece at Publishing 2.0 about what he calls the “web content conservation movement.”  In this day and age, between websites, blogs, Twitter and social networking sites, there’s way too much online content out there for any of us to keep up with even a fraction of it.  So Karp suggests that rather than posting anything that pops into your head, post only what others would find interesting or useful (or, I would add, amusing).  Add value to your post by including a link so instead of creating something completely new, you’re directing traffic to something that already exists.

What this means for authors who blog / are thinking of blogging but who are intimidated by the time commitment, is that blogging doesn’t need to take a lot of time.  A successful blogger needs to provide readers with regular posts, but rather than always having to sit down and produce original posts, an author blogger also has the option of simply commenting on someone else’s.
