From the article:
The word “curate,” lofty and once rarely spoken outside exhibition corridors or British parishes, has become a fashionable code word among the aesthetically minded, who seem to paste it onto any activity that involves culling and selecting. In more print-centric times, the term of art was “edit” — as in a boutique edits its dress collections carefully. But now, among designers, disc jockeys, club promoters, bloggers and thrift-store owners, curate is code for “I have a discerning eye and great taste.”
Or more to the point, “I belong.”
For many who adopt the term, or bestow it on others, “it’s an innocent form of self-inflation,” said John H. McWhorter, a linguist and senior fellow at the Manhattan Institute. “You’re implying that there is some similarity between what you do and what someone with an advanced degree who works at a museum does.”
