All sarcasm and cynicism  notwithstanding,  this  is a good idea--we need a public space at the center of town and this  renaming will encourage  greater respect and more productive use of the area.  We've heard a lot of great music there in  past summer evenings and can expect more now.
Regarding Mike Clark's concern that "it's not  inclusive  of who we are"--
Ken Kesey was a great writer, penning two of the Northwest's most famous novels; and 
Ken Kesey was a creative founder of the Counterculture; and
Ken Kesey was a natural-born Oregon country boy, and "Sometimes a Great Notion" captures the essence of  traditional Oregon logging culture.
Not inclusive?  The only folks Ken Kesey didn't represent were the local  stuffed shirts.
