I’d like more of that traffic so I’ve come up with an idea and a plan that will serve all of us . How about if those of us who are Math bloggers tweet each other’s blog articles Friendfeed makes it easy to create a private invitation only group where we can post our latest Math blog articles so I’ve created such a group . The commitment for anyone in the group is to tweet a large percentage or all of the links members post . If
