#D_lang vs #Dlang hashtags

On a somewhat related issue, how does one search for something 
related to D on the Internet?  I'm mostly talking about quick 
technical questions here, like "how does one use X feature, or Y 
library function, properly".

I've found googling for "site:dlang.org <my question>" to be most 
useful for now since this includes the mailing archive.  However, 
this does not include several other meaningful alternatives such 
as StackOverflow.  And Google does not generally recognize "D" or 
"Dlang" as good as it does "C" or "C++".  Any suggestions?
