"Things" that make you go CTRL+D

I am starting today a new section named " 'Things' that make you go CRTL+D ". In case you don't know, CTRL+D is the keyboard shortcut that, on a PC, gets a certain webpage into your bookmarks (or favourites or however your browser of choice calls them). The posts under this section will have the tag CTRL+D bellow and will talk about webpages that called my attention. I will be mostly treating about bands I discovered on the net, but some other web pages might also fit in.
