concern about journal and book reviews

I'm concerned that there are too many book reviews in my journal... that's not what a journal is for, right ? A journal is also for your thoughts, for the stuff you did, etc...

I post a book review right after I finish reading a book, and I obviously read a lot. So, there are a few solutions:

1. Read less - nah....
2. Post book reviews in some other place. I already tried that, and it's burdensome. Here is by far the simplest.
3. Don't post all book reviews, only those I see as important. Will give it a thought
4. Post more of other stuff

Oh well, I've gotta think about this... in the meanwhile, I have another review pending - "The cashflow quadrant", I'll probably post it tomorrow.
