I'm a member of the Chuck (tv show) community. We encountered similar issues in trending efforts. Some hash tags will simply not trend, and there's no apparent rhyme or reason. Twitter support never responded to any inquiries as to why some seemingly innocuous keywords (like #SaveChuck) would not trend, but others would. I assume they have their reasons, and as a free service they have no obligation. It's still annoying for the user community.
