To get a blog on the Recent Wiki Activity page, all you have to do is post it, update it, or have someone or yourself post a comment on it. Because, as it explains, that's recent activity to the blog.

Also, another piece of information, if you want a blog on the Popular Blog Posts Section, it has to have the most comments in 3 days.

Let me know if you have any more questions :)
