They have done a great job so far and have been working to get a broader diversity of Spanish posts, which have been increasing greatly since they started the Cervantes project. Curie has other Spanish-speakers reviewing those posts, so there's no danger that any one or two people "control" curation. If the volume of posts for Cervantes increases more, then I'm sure they will look for additional help with curation.
