The Anti-blog Blog

I have been invited to post a blog every other Tuesday at Writers Who Kill. http://writerswhokill.blogspot.com
This is a big honor for me since it means someone out there thinks I am a writer. I managed to get my introductory post written and submitted and my post for this week ready to go a couple of days early.
I started the blog here on Goodreads to see if I could do it since it looked like a must for writers. I have missed three weeks since I started.
I keep in touch with other writers and it seems that fully half of their word count if for blogs. Some of them write several blogs a week.
Does anyone read all these blogs? Is blogging taking the place of reading books? How long can I keep this up before I run out of interesting things to say?
