Should we blog in the classroom?

In a few weeks, our English Department will have a poster session on "Best Practices" in teaching. Mine will be on using blogs and wikis. Of course, I present the usual rationale for using blogs and wikis, but for me the highlight of presenting this poster was reviewing my students' blogs and seeing again how they were able to tie their writing into their own interests. One of my students, for example, has an active interest in things Japanese, applying the name "yukiseguchi" to her blog. She wrote about how to wear a kimono ("Flutter your sashes") and geishas and inserting great images, too.

Despite appreciating my students' posts, one thing still troubles me: Few of these students continue to blog after the course ends. Nancy McKeand (Random Thoughts) asks, Why aren't we all blogging?. There's no easy answer, but it's unlikely that we're all made from the same mold. Some like sports, others music, and others, still, video games. One of my students moved from blogger over to myspace, where she is still active.

Perhaps we shouldn't worry about whether students like blogging or continue to blog. When in high school, I enjoyed basketball, but I didn't like the speed drills. However, they were great for developing my stamina. And perhaps that's how we should consider blogging. That is, Is there some benefit from blogging? Besides, we could also ask how many of our students continue to write essays after graduating. Should we, then, stop requiring essay writing? Hmm. I'm assuming that writing essays has some benefit. Does it?
