Finally I wanted to raise one other troubling observation re: the LOD Cloud, which was that *only one new dataset was added to the LOD Cloud group in datahub over a period of twelve months* [2,3]. Jerven just added the first dataset in 8 months, presumably due to this ongoing discussion. One can scroll back in time arbitrarily far in the activity log of the group to see precisely how much activity there has (not) been [3] (e.g., Ctrl+F for "created"). It's not comfortable reading but I think that we, as a community, should seriously ask ourselves: why there has been so little new activity?[1] Tobias Käfer, Jürgen Umbrich, Aidan Hogan, Axel Polleres.

Given the state of CKAN, or at least the version that's running datahub.io now, looking solely at the lodcloud group [4], may be misleading. I can't recall exact dates now, but, there has been a number of important changes in the past which made it difficult to pick-up on the lodcloud-worthy datasets. For instance, when organizations [5] were introduced, datasets dangled around in the global pool. To "reclaim" them, you had to create an organization and move the datasets over, with permission from the datahub admins. AFAIK (things may have changed) you can't have a dataset that belongs to an organization and have it also assigned to a group. I suspect that, many (myself included), would prefer to manage the organization instead of handing it over to group admins. So, this may partially be the reason why the lodcloud group is not as active.
