Scientific blogging - a key issue with scientific blogging is the representation of formulas. I have built a simple tool which converts a Word document with equations into a XHTML+MathML document. So it would be possible to type up the blog entry inside MS Word 2007, and then run this tool to create an XML file (actually an XHTML file) with the formulas represented as MathML and the remaining content simply coming from MS Word's conversion from .docx format to HTML format. Retaining the meaning of the Math content as MathML inside these XHTML documents would then allow searching the mathematical formulas.
