Found a great story on BoingBoing about how authors use their blogs.
For those of you who don't know, commonplace books are/used to be journals where you listed interesting info, new words, well-worded quotes, etc. I have one on my computer and a few from pre-computer days.
Consider yourself lucky. I've started a new book every couple of months due to getting distracted, new idea, etc…etc… I must get about 1/3 of the way in, then think of a new idea and start a new one. At least you've got one thing going. I'm going to end up with a compilation of unfinished stories. All plot – no ending!
