You might have noticed it. From now on comments on posts can be made through disqus. As disqus is used on many blogs and the login can be made using facebook, twitter, openid and many more it should be no problem for people who want to share their thoughts.
If you don't like disqus, you can always email me at sebastian (dot) goettschkes (at) googlemail (dot) com. I'm happy to discuss various topics through email, so feel free to drop me some lines.
And, of course, I hope to get more comments now that disqus makes it easier to enter the personal information!
