The facebook message came first, from a friend and avid facebook user. He told me later that he thought something terrible had happened on Temple's campus, and that I changed my profile to show support. This goes along with participation through media, such that it is common for people to alter their profile pictures to show support or take sides on a popular controversial topic. 

The first two commenters showed their confusion with minimal words, one using a word modified by the internet ("wat" from "what"). My high school chemistry teacher gave me the response I was expecting, as he asked if I was going to Temple. He is more blunt than others on facebook, which was helpful to get a sense of what others might be thinking. They may be censoring what they put on facebook, just as I do.

The next two commenters are people I see often, and commented with inside jokes because they know me well enough to see this as a random change, and not a meaningful one.

The last comment came within the last 24 hours, and was from my mom. I glad to see she saw this, as her reaction was interesting. She usually comments in full sentences, possibly because she is used to writing emails, but instead she commented "???", showing greater confusion.

Overall, it seems that my less concerned filter in what I post lead to some interesting reactions. It also lead to comments that were characteristic for some, in the case of my chemistry teacher, and uncharacteristic, in the case of my mom. I discovered that the filter I put on the content I post is well placed, as my facebook friends take concern over the meaning behind this post. For some of my facebook friends, facebook is our main or only point of contact. By posting things that I may want to in the short term, may confuse or concern people about my livelihood in the long run. If I were to repeat this experiment, I would see the result of not explaining myself directly after their comment. This way, I might be able to see more than just their immediate reaction, but possibly some interaction between my facebook friends about the profile picture change.
