I've added the original list of Big5 URLs from <dotnetdotcom.org > to  
<https://gitorious.org/whatwg/big5/blobs/master/big5-urls.txt> and it  
contains 140 .hk URLs and 133 .tw URLs. In other words, the sample does  
not appear to be unfairly biased to HK, it was just that the pages using  
the conflicting byte sequences were mostly HK-related.

Bigger and more random dataset would be awesome, if someone could/produce

Merging Big5 and Big5-HKSCS is not a goal in itself, but we must decide  
what mapping <meta charset="big5"> should use. Is there any mapping that  
would fix more pages than the one I've proposed?

Right, I assumed that "Telnet BBS" was not exposed to browsers, but  
perhaps I guess that was in reference to ptt.cc?
