Twitter hashtag for D?

[MIURA Masahiro]

Is there a common Twitter hashtag for D?

If there isn't any, how about #dlang?
#D and #DMD give too many false positives,
#D_programming_language is ridiculously too long.

I guess that Twitter is not very popular among D fans
(http://www.digitalmars.com/d/archives/digitalmars/D/announce/Anyone_use_twitter_for_D_14287.html)
, and that serious discussions should be kept in newsgroups.
On the other hand, I don't see anything wrong with posting simple tweets
like "new DMD release, yay!" on Twitter.
It's a small contribution to what Walter called "social proof" :-)
