Thinking about Semantic Web, crowdsourcing and mostly after reading a recent blog post from Andy I came to believe that we need a ‘Tagipedia’ (Wikipedia for tags): a place where anybody can tag any uniquely identified web resource (URL) and thus gradually, collaboratively describe the entire Web in more semantically sensible way.

Ironically, large social-bookmarking services (e.g. have enough data to start something like that, but they have not exposed it in a meaningful way, yet. What we really need is an API call that would return top 10 (or 20) most common tags, across all users for a specific URL. Given that all kinds of widgets can be built, including browser-extensions., where art thou? Can you hear us?
