There's been much debate about revising the rules for the Hugo Award, but there's one aspect that everyone has either missed or been afraid to touch.
Some history:
The then grandiosely named World Science Fiction Convention started in 1939, with about 200 people.  It wasn't held during WWII, and it stuck to larger, American cities--New York, Chicago, Philly.
The first one outside the US was Torcon in 1948.
The first one outside North America, was Loncon in 1957, thus finally making a valid claim of "World" after 18 years.
In 1970, Germany hosted, bringing Europe into the SF "World."
Australia came on board in 1975, actually bringing in another hemisphere.
It wasn't until 2007 that Asia merited note, with Yokohama.
Now, an astute observer will notice that all those countries are progressive, wealthy, nations of privilege, mostly Western, and certainly all in the upper echelons of economic success.
Supporting memberships at this point are $40 US.
There are people in the US for whom $40 is a stiff part of a budget.  Beyond that, I just heard from two of my fans in India and Bangladesh. My Bangledeshi friend works for their DoT as a senior engineer, and earns a princely $150 a week.  He's managed projects where the repair cost for the road was estimated at a half million, and been told, "You have $5000." (Adjusted to US currency.)
I send Najmul e-copies of my books for free, because not only can he not find them, he couldn't possibly afford them.  He's currently doing some training in Australia, and glad to be there, since he has much less worry about roving gangs, or if a neighboring country will build another dam and cut off his water supply.
He bought a supporting membership at $50 AUS, being most of a week's disposable income for him--and remember, he's one of the better paid people in that country--and since he's a fan of several others, we've all sent him a large package of SF to read, electronically.  I informed Brad Torgersen, and quite a few of the other writers he has promoted are doing likewise. I will also forward any ebooks from other known authors to him.
But, a "World" con should be more accessible to the world.  SF fans in developing or struggling nations should not have to balance a supporting membership, to an event they can never afford to attend in person, with daily necessities.
If you look at the membership lists for any Worldcon, you will find almost no participation from Africa, East or South Asia other than Japan and Korea, or much of South America.
I propose a supporting membership should be $5. It's arrogant and elitist to proclaim to be a world event, then to price three fourths of the world out of it.
This will need to be brought up at the WSFS business meeting and voted on.  On the one hand, it will mean less money per supporting member. On the other hand, it will mean more members, more inclusivity, and a better reach of SF to the world as a whole.
It's time to put the World into Worldcon.
