Okay, I've decided... and this time, I'm sticking to my decision:
I've disabled Disqus.
It was proving to be more trouble than it was worth, chewing up people's comments, failing to notify me when someone had written something and sending everybody else's comments to people who hadn't even selected the 'Subscribe To Comments' option. Like I said before, Blogger's system may be basic, but at least it works.
The awful thing is that I appear to have lost every single comment everyone left since the 14th of February. If you were kind enough to take the time to write something, then I'm sorry to say that your pearls of wisdom have vanished. I do hope this doesn't discourage you from writing something in future; I always appreciate everyone's thoughts and insights.
Disqus be damned!
