To Review or Not to Review, or a Fellow Book Blogger Needs Your Opinion

So I've had my blog for about a year now.  I've enjoyed it, and I look forward to many more years of blogging about great books.

Here's my dilemma-my reading time has shrunk to almost nil.  In the past two weeks I have not finished a book.  This fact makes me cringe.  I was reading a book, One Day, by David Nicholls, for my book club.  Problem was, I didn't like it, so I kept putting it down.  I wrote a post last year about giving up on books I'm not enjoying, but since this was a book club book I figured I was obligated.  Well, not only did I not finish it for book club, I finally gave up and started another book, which I also haven't finished.  I just don't have as much time to read at this time of year, especially this year.

So, what to do about the blog?  I don't want the blog to sit here idle while I am not able to do as much reading.  I enjoy the community too much to be that disconnected, and frankly since I started a blog so I'd have an audience for my writing it would be nice if people were still around after this fallow period to read it.  Thus my question:  should I start writing reviews of books I read years ago?  Is that somehow cheating?  Will anyone care to read them?  If this blog is supposed to be an electronic book journal, does it make sense to start going backwards rather than forwards?

I know, I know-it's my blog, I can do what I want!  But I'm curious what my fellow book bloggers think.  Do you ever go back and review books from your past?  Do you think of your blog as a way to let people know about what's new, or do you review any old thing you read regardless of when you read it?  Do you ever recycle reviews?
