I think it's the reverse.

even if China doesn't block the access of google.com.hk, individual who search (or do anything online) inside china can still be traced. I think the move to redirect search to google.com.hk will immediately reduce the usage of google, cos the general public, who knows a bit of what is being censored, may prefer not to see these materials at all.

still don't get it? imagine there's a search engine that returns NSFW materials for sure. will you use it at work? will you avoid using it?

yes, there's internet cafe. but there's highly efficient people's police, and net cafe owners who won't think twice to report to the authority.

go for a real press with open access, say http://www.aupress.ca/index.php/publish/ . the advantage is that library over the world probably wants to buy a hard copy from a real press, and you can let those online user to use the book online, plus a channel to sell hard copies.
