Including LaTeX code in blog postings can be challenging due to issues with the LaTeX preview feature. Users have noted that the LaTeX icon may not appear in the blog editor, limiting access to the drop-down menu for easy insertion. Instead, users can manually enter LaTeX code using [tex] tags, although the preview may not function correctly. After submitting the post, refreshing the browser can help display the LaTeX properly. There are indications that LaTeX may not work in blog comments, but it should function within the blog itself. To ensure proper formatting, some users suggest creating LaTeX in an environment where preview is available and then copying it into the blog.
