look up any word, like the eiffel tower:
The layer of social web services that enable users to interconnect, tag and cluster classic websites.

Origin: from the Greek word μετά (metá) (meaning "beyond" or "after") and the world wide web.
The site where the information was first made public was an obscure university blog concerned mainly with local matters. It's server buckled under the onslaught of visitors that resulted from the article's exploding popularity in the metaweb, especially Twitter.
