The current PortlandWiki logo, in use since April 2010, features a stylized rose in reference to one of Portland's nicknames, the City of Roses. The "petals" are arranged in a confluence pattern to emphasize the collaborative nature of wikis. The petal shapes were adapted from elements in the Portland flag.
The logo was chosen from a number of candidates at a Wiki Wednesday meeting. During the development and selection process, feedback was openly solicited on- and off-wiki. This feedback informed the creation of the logo candidates and the final consensus decision.
The logo replaced the old "placeholder" logo which was meant to be temporary until a more suitable one could be developed and confirmed by the community. The old logo was designed before it was determined that "PortlandWiki" was one word.
