I joined Goodreads back in the fall and I've been endeavoring to put up a few reviews a week. This effort has mostly gone unnoticed but in the last few weeks I've gotten notification of two "likes" on a review I wrote.
Interestingly, both are for the same review. The Human Predator: A Historical Chronicle of Serial Murder and Forensic Investigation. The book was interesting (provided you're interested in the darker side of humanity) but encyclopedic at times. The author had an interesting theory that serial killers play out unacknowledged cultural tensions but didn't go into details as to why she felt this was the case.
Either way, it's still encouraging to note that my little online profile is growing.
