Adding comments from the blogosphere to molecules. Screenshots from the PubChem web page for methane (full URL: ), (a) without and (b) with the "Add quotes from Chemical blogspace to molecules" userscript enabled. The InChI InChI=1/CH4/h1H4 is identified by the userscript, which then adds the Cb logo. The logo is a link to the Chemical blogspace page for this molecule. The popup titled "Powered by Chemical blogspace" (only partially shown) appears when the mouse is placed on the Cb logo, and contains quotes from and links to blog posts that discuss this molecule.
