ppl don't know what "nj" and "wd" mean?

When talking about compliments players keep mostly repeating "gj" and sometimes say "nice" or "wp". But no one ever says "wd" as in "well done" or "nj" as in "nice job". And when I say those no one says anything to them. Are the "nj" and "wd" abbreviations totally unknown to this community?
