Greetings fellow Cascadian Wikimedians!
I was just chatting with Frank Schulenburg and Renée LeVesque from the Wiki Education foundation. They are involved in helping do some of the organization for WikiConference USA 2015 right now and trying to nail down venues.
Seattle is listed as a possible venue on this page:

I told them that based on my reading of the conversation on this list, there was interest in considering hosting Wikiconference USA in 2016 but a sense that we wanted to host some more local/regional events and get established in 2015 and did not want to be seriously considered as a host for this coming year.
If somebody is really dying to help organize the full deal over the next months, speak up and I will let them know. Otherwise, I'll go ahead summarize my reading of the general temperature in our group on that page.
Regards, Mako
