PSL ListServ Streamgraph

Has the PSL ListServ lost it's mojo? Short answer, no. But take a look at the streamgraph below to see the ebb and flow of various words used by the community. It seems that the amount of times the word "help" is being used has significantly increased relative to other categories this past month. This means people are using the word "help" in one of two different situations: one where people are asking for help, the other for giving help. Without going into each email containing the word help and highlighting each sentence, it's difficult to know whether asks or gives are occurring.
