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.
