1) Tools suck. Even today. Unmaintained tools from 2003 are still used as examples, which is a shame.
2) Having multiple vocabularies is a good thing in principle, but clashes with the "simple integration" selling speech. Have you tried to different data using different vocabs? (assuming they are using the vocabularies correctly, which is far from realistic in many cases).
3) On important selling point is the reasoning and inference part. Sadly it is not available by default in most tools I've used. In fact, there are really very few tools that deal with that and usually are a pain in the ass.
4) Despite all the academic hype regarding RDF-backed CMS, there are very few frameworks that actually work. Drupal 6 and 7 claim to use RDF but honestly, RDF doesn't add value at all
Just to make things clear, I've developed tools and being an advocate of Semantic Web for years, but I'm also a critic person. We have to acknowledge that in academia, tools reach a buggy, prototype level that make them unusable in real world environments. I know there are a few companies that do a great work building semantic web tools, but I'm afraid they are the exception to the rule.
