First, I strongly agree we have a lot of work to do to make our comment and TrackBack management tools better. We are working hard on that, and will talk more about that when there’s progress to show.

I’m not sure at all what you mean by duplicate content on TypePad. If you mean that spam bloggers are taking popular blogs’ content and republishing it, that may happen, but that can happen with every platform, since they’re just republishing RSS without permission. I don’t know of anything particular to TypePad which makes that worse, and I’m not sure the context of your conversation with a member of our team, but I can’t imagine there’s an issue affecting our bloggers’ appearance in Google that we wouldn’t address. My mobile phone # is 646-541-5843 if you can explain more about that, or just drop me an email.

As best I can understand it, you’re talking specifically about Technorati, and more specifically about the method they use to determine uniqueness or sameness of blog content. Honestly, we can’t make changes to their code, so it’s not something we can address. I do note that other blog search services tend to understand domain-mapped blogs, so it must be possible to fix. It doesn’t seem to be something we could change on our end, and I can’t imagine it has any substantial impact on blog traffic.

Although I understand if it’s just the ego part of wanting to see a bigger number next to your name on Technorati, since I’m a blogger myself.

I do understand some people don’t like file extensions. I do, so they’re there. That’s just personal preference, and I’m not a big fan of fetishizing URIs. MT certainly supports publishing without file extensions, and always has, and in fact lets you do things like create .asp or .php or .jsp files, which is tough to do on other platforms.

There may well be topics where I could have been more pointed in my description of WordPress; My intent was not to denigrate that platform, but to speak to what we do well. I’ll leave the criticisms to people who are members of that community and who have a vested interest in it — the feedback about what we need to do better on MT and TypePad is what has the most utility to me. I hope that helps.
