A lot of us bloggers have been struggeling with the blogger comment system. So have I, so I chose to go for Intense Debate. This sucked too, so now I'm on to Disqus, something that works as far as I've experienced. I've noticed that I got way less comments on my posts since I changed to Intense Debate. Or my blog just got boring haha. So now I have Disqus, which seems way better.
I hope this works now!
