What are your needs for editing and rendering equations or formulae on Web 2.0 sites? Social networks and Web 2.0 sites are the ideal forum for sharing, but they are not geared for academic use. Academic discussions would be considerably improved if Web 2.0 sites would add just three buttons: Superscript, Subscript and Greek letters to the HTML editing toolbar. Perhaps we should ask Ning and other social network providers for better support for this feature, and the square root symbol too! One solution is to use an online equation editor, as at CodeCogs or Thornahawk, to generate an image of your equation. For example, the expression "\frac{-b\pm{\sqrt[]{(b^2 - 4*a*c)}}}{2a}" renders the formula for solutions to the quadratic equation a*x^2+b*x+c=0. I uploaded the rendered image "Quadratics_Solutions.gif" to this blog post. This topic is now being discussed at Mathematics24x7.ning.com and on the Math, Math Education, Math Culture group at LinkedIn.com. A more detailed article, with links to technical solutions, is on my blog at Vox.com.

I submitted the following feedback to Ning at http://getsatisfaction.com/ning
Need Simple Equation Editing in the Ning HTML editor
Students and academics need to edit and render equations or formulae on Web 2.0 sites. Discussions about mathematics and science would be considerably improved if Ning.com would add just three buttons: Superscript, Subscript and Greek letters to the HTML editing toolbar. And the square root symbol too!
