a better way to write Blog

I found a very good online editor, zoho, which provides much richer formats. You can just used as an alternative to Word or WinEdt. Combine it with codecogs equationeditor, we can write blogs with complex equations easily. My previous post is done with these tools.

Later on, I found it is best to use zoho exclusively, because zoho can export your file in Latex format that can be reused in your other documents. codecogs also provide Latex code, but we need to add some HTML codes to put it to our blog, which make the blog messy. But zoho has no such problem.
