Well, it seems that Google's Blogger is having a tough time showing everyone's comments on each post. And this is not the only blog with this issue. In fact, from what I can tell, this is a known issue at Google, and has been for many months, in fact over a year.
I know that Blogger is free and all, but it's just sad that Google has not been able to resolve this known issue for so long. Especially since they certainly seem to be able to keep all the comments active in their help forums, so obviously they how to make this work somewhere. In the meantime, I wanted all my loyal readers to know that I am getting email notification of your comments, but sometimes no comments will show up on the actual blog posts. It's really hit or miss.
Sorry about that. I will do more research into this and try and resolve it as quickly as I can. If I can't get it resolved soon, we may all be making a trip over to WordPress to get this running correctly again!
