I guess Tom gave already an answer to your question: microformats are not in the web of data (nor are they linked data), they are just well structured (and easily accessible in the web environment) records of atomic ground data.
I happen to agree with both comments: there is a difference, but let's people find their own way autonomously: "Letting a hundred flowers blossom and a hundred schools of thought contend is the policy for promoting progress in the arts and the sciences and a flourishing socialist culture in our land."
