my social network sphere is fairly limited. facebook and this blog are the only vehicles i use regularly, though i do have a tumblr account that i update every once in a while, a flickr account i haven't updated in years, and a twitter account without a single tweet. a dabbler at best, i wasn't entirely shocked when i came across this periodic table and discovered that there are quite a few sites i know nothing about. while i haven't the time or the inclination to grow my wee sphere at the moment, there were a couple of really interesting sites on there, particularly some of the music ones, so i'm posting it here for you. click on the picture to be taken to the site where you can click on each symbol.
