I think we're all approaching this question wrong. Rather than make the site easier to access on Google, why not go for an easier approach and try making the site easy to find through social media. Building a good website is hard, totally restructuring an old one without losing data is harder. On the other hand, constructing an easy-to-read, attractive looking Facebook page is incredibly simple.
I suggest that we reconstruct the Santharian Facebook from little more than a showcase for our art to an active advertising effort. This means members need to spread it as far as possible as quickly as possible.
It also means we need something to advertise. We have a lot of stuff here, but we can't advertise already written work. What we can advertise is empty space. We need to be able to say to potential developers not, "Look at all this cool stuff we've done," but rather, "Look at all this cool stuff YOU could be doing."
To this end I'd advise something like opening up a new continent or the like: we do have three continents with exactly 0 development after all. Of course, we'd write the framework for this new development space as a massive group project. I wouldn't dream of loading it all onto one person.
Any thoughts?
