Not sure about the RSS design decision, it pretty much restricts
the resource types to documents, so we can't really use it as an
"umbrella" spec. My 2 highly redundant cents:
- I found DOAP to work fine for most things software, DCMI provides a 
  number of handy resource type URIs[1] which could be used to augment
  doap:Version resources (e.g. dctype:Collection, dctype:Dataset,
  dctype:InteractiveResource, dctype:Service), or owl:Ontology for
  projects that produce vocabularies (e.g. the FOAF project)
- tags (skos:subject, or dc:subject) for more specific stuff (personal
  preference: the more fine-grained skos options)
- Danny's review vocab[2] for ratings/reviews
- a combination of the two rdf/iCal specs[3][4] (with and without
  timezone-datatyped timestamps) for events
