The banner image at the top of this blog is a picture of street art graffiti that I took on a recent trip to Montreal. I chose to use this image as the theme of this blog is networks. This image represents the secrecy and exclusivity of many networks. Street artists do not openly identify themselves so only through close trusting relations can members become network members. Graffiti writing in itself as an art form uses symbology and art to portray messages that may only be understood by other network members. The writing also symbolizes to those outside the network that criteria of talent, knowledge, cultural understanding and lots of guts to perform illegal acts are at minimum criteria for network membership. This image is a way to remind me that while some networks seem fluid, all require a certain level of criteria for membership, none of which should be ignored as outside membership means that salience may never be assessed properly.
