I thought I'd be clever and install Disqus comments plugin on my blog, replacing the native blogger system. But it was a mistake for two reasons:
Firstly, there is a technical glitch that arose about 8 months ago due to to some issue with blogger going from an http to https address. This split my comments into two separate streams. You can still see all of the older comments on the disqus site but they don't properly appear on this blog anymore. I don't have the time or desire to learn how to resolve this issue.
