I decided to give Disqus a try. It's been recommended before, and often, but I was just too lazy to bother with the change. Amusing Bunni mentioned it again so I thought hey, worth a try. It lets you reply to specific comments rather than just adding another one at the end of a long list. Might make it easier to follow conversations.
It 'says' it's importing the Blogger comments. There are a hell of a lot of them so it might take a while.
We'll see how this works out. If it's crap I can revert to Blogger. All your comments are still there on my Blogger screen.
Update: That was quick. The order is a bit jumbled but new ones should follow a proper thread pattern.
We'll see how this thing pans out. If you use NoScript you might have to 'allow Disqus.com'. If you block all cookies you'll need to allow disqus.com in the 'exceptions' list. Couple of clicks.
