ASM is giving away a handy reference of the top media sites – check here http://goo.gl/peME . You won’t be surprised by the list, but its a handy reference to make sure no social sites slip through the cracks of your marketing strategy. Contains a URL, Category, Description and Alexa Rank. I’ve found the ASM to have a number of useful tools and services. Take a look at their offerings, membership is $300 per year.
