We now have more than 200 rock-identification questions. Here on meta, we have a very good guide on what it takes to write a good rock ID question. It doesn't take a geologist to recognise that many rock ID question are very far from meeting those guidelines. Those questions need to be either improved or closed.
I propose that the community undertakes an effort to make sure that we don't have any old and open rock ID questions that fall far short from meeting the guidelines. As a diamond pro-tem mod, I could close some of them myself, but to grow as a site we need a vigilant community of high-rep users to take care of this, in particular because ultimately it takes domain experts to really determine the quality of questions and answers, in particular on a site covering an interdisciplinary field like ours.
