I was looking through blogger's help pages and discovered this article about promoting your blog. (It's not what I was looking for but it looked interesting so I was, naturally, sidetracked.)
The author, Biz Stone, suggests three types of promotion. I've mostly done the steps suggested in "Blogger Application Settings." They involve chosing certain settings to allow people to email my posts to others, setting my blog to ping weblogs.com, etc.
The other ideas were new to me. "Blogging Technique Suggestions" include making regular updates and writing quality content. (Damn, you mean I have to work at this?)
The best ideas were in "Marketing Action Items." There are nine different ways to promote your blog. Some are as easy as adding your blog address to your email signature. Others use terms that are totally new to me like "meme games," which sounds kind of naughty. The only difficult one sounds like adding a blogroll which they say you can do here. (If you can't tell, I've recently learned how to do hyperlinks. Since it's the only thing I know....)
Well, I should probably get back to teaching! Anyway, it's probably being presumptuous to think people would be interested in what I have to say--but you never know.
UPDATE: Here is another article about increasing traffic by Biz Stone. I posted it here so that I don't have to go looking for it again when I'm actually interested in increasing my traffic.
