Many of your posts are very good. I like them very much. Thank 
you.

I haven't played with `wiki`. However, Maybe we can `organize and 
display` good posts according to `"author/category/label"` and 
put them in the `documents`. In this way, "d" novices can also 
use it offline to learn from them quickly.Because many posts are 
practical examples.It's very good.

Moreover,`d` officials should reward `excellent posters` like 
submitting PR and encourage  excellent answers.

In this way, `D users/D expert(with good posts)/D language` all 
win!
