Closing comments after 30 days

I’ve changed the settings on this blog, so that comments are automatically closed on a post after 30 days.

I’m making this change for two reasons:

1. There are too many spam comments, mostly on older posts.
2. I rarely get comments on old posts anyway.

For the present, I’ll leave all comments open on my other blog (on computer), because I do sometimes get comments on older posts there.
