We have: "D" the programming language [0] "D" the data language specification [1] "D" the programming language for DTrace [2] "D3" the javascript library [3] "D4" library/tool for Declarative Data-Driven Documents[4] "D4" implementation[5] of the data language specification[1] Overall, I think "D2" is objectively the best choice here. We have at least three "D"s, two "D4"s, and one "D3", so it makes sense to put it in as "D2". I certainly wouldn't want another "D" or, heaven forbid, a "D5".
