Change the world or go home?

I really like Hugh McLeod's blog.  I can't decide whether I like this post or the cartoon above it more.  But anyway, regarding #20:

Blogging will never be a mainstream activity so long as being able to write [A] well, [B] often and [C] about stuff THAT PEOPLE ACTUALLY CARE ABOUT remain the main barriers to entry.

Thankfully, these barriers go away if you don't care too much if anyone is actually reading!  (Or if you're targeting a very specific audience, like friends and family.)

So to answer the question in the title, as far as blogging goes the answer for me is "go home".
