Does anyone subscribe to this service? is it worth it? what all is in this service?

I've been a PBSer for only a month.  I tried the free trial week and then signed up for the year.  I did it only for myself.  I don't mark the "make public" or whatever it is.  I did it to see if this would help me remember what I read.  Normally I forget the last book as I read the next book or so.  I don't know if this will help me or not but I thought writing some things down might help.  I could have done this on paper or just on my computer, but doing it on the web site (even if it's just for me) will probably make me keep doing it.  It's just like one more thing to do--journal the book as soon as I've finished it. 

I subscribed to the Book Journal a week ago. I thought it would help to keep track of what I read. I think its easier to keep track by writing the book and information in a notebook. I have it for a year, but don't think I'll re-subscribe again.
