A lot of the conversations on Dreamwidth aren't about getting things done - I heard it described recently as being like the office water-cooler - this is where we have casual chats in between work. Sometimes it drifts into chats about work, and some communities are more work-oriented than others, (e.g. dw_dev, dw_wiki and dw_suggestions) but the actual work (whether docs, support or coding) tends to go on behind the scenes - in the other IRC channels, in PMs and emails, in internal comments on support requests, and in Bugzilla.
