Although the list below is specialized for math bloggers, they can be used by bloggers of any field. I have used all the software below,
- WordPress. WordPress is a free blogging site. Upgrade is available (for a fee) for larger storage and domain name customization. I chose WordPress to host Mathematics and Multimedia mainly because of its Latex support. As of this writing, as far as I know, two of its top competitors, Blogspot and Typepad, do not support Latex yet.
- Google Docs. Google Docs can be used to store and share documents online. It has its own word processor, spreadsheet, and presentation software. It has currently released a new drawing software. You can use Google Docs to store your documents and link your blog to it.
