If you'd asked me, I would have guessed that SLP tends to weaker words that are somewhat negative, as mild criticism is a common theme for me. According to HotStuff 2.0 for Science Library Pad however, I apparently tend to medium-strength, positive words (in the plot below, lower position is stronger words, right is more positive words).
HotStuff actually has all kinds of cool information about library blogs, including word clouds and geographic references - a great example of making the blog data work hard. There are also daily summaries in the HotStuff blog.
