**Math, Math Education, Math Culture**, the popular discussion forum on the LinkedIn.com social network has achieved 1000 registered members. The discussions cover a range of topics from philosophical contemplation of the "Effect of math on human cognition?" to a humorous look at a school maths problem, "The mean weight of 50 students in a class." The forum was created in September 2007 by Opher Liba, an educator, researcher and author. LinkedIn.com is not the kind of social network where you would post a photo of your pet cat. It operates more like an online CV or resume, with some incidental features for networking with other professionals. It does provide about a dozen third party applications, such as sharing Powerpoint presentations, or posts from your blog, but these slow down the website. Alternative meeting places in cyberspace for mathematics enthusiasts include: http://mathematics24x7.ning.com/ (almost 300 members) and Mathematics/Mathematik in German and English on Xing.com (almost 2000 members). These sites are free of charge, with optional extras for paying members. Facebook has discussion groups like I HEART MATHEMATICS (over 2700 members), with discussions such as "Funny Math T-Shirts." The Facebook group Mathematicians ONLY! has over 1300 members, some of whom are brave enough to discuss the "Definition of a Mathematician".
