It's a glitch with blogger it seems if you use Windows Live Writer to write your posts (which I'm doing right now, because it's way easier to use than anything solely web-based).
Comments are here though and will stay here, it's just they're using the old blogger system rather than (my preferred) Disqus system. I guess when they've found a work around, I'll be able to do something about it. It looks like I'm not the only with the problem having done a bit of a Google-around.
Rest assured, I *do* get round to reading all the comments (eventually), however they come in and I appreciate that you take the time to both read and comment on my blog. And I hope you continue to do so.
