In the matrix nobody can hear you scream. You don't have to anymore to rise up out of backwaters, backstreets, ghettos and favelas; to be seen and heard far, far away; to be eminently discoverable from Tribeca to Trenchtown to Tokyo to Timbuktu.
Because in the matrix, everybody is somehow accessible from everybody else. All roads lead everywhere. Operating within a matrix removes boundaries, builds bridges and opens up the universe of the arts as its never been open before (full disclosure: our original motive in building the matrix was to provide a cost-free means for wonderful musicians in Bahia to be heard beyond the backwaters and favelas -- ghettos -- of Brazil).
You recommend people by clicking on the categories they create for themselves (on their They Curate Me tabs). You can likewise be recommended for (music & arts related) categories you create for yourself. If you wish only to recommend -- and not be recommended -- simply don't create your own categories. One can follow recommendations without signing up.
Recommendations/curations in series form worldlines, travelling in steps, leaps and bounds. Worldlines taken together form the matrix. That would be "matrix" in its original sense of "source", from "mater", Latin for "mother". We're a real mother for ya!
