MaintenanceA few days ago Matt at Webmaster-Source and Michael at Pro Blog Design published articles about optimizing the load time of a blog and plugins to get more comments

Influenced by their articles I decided to review and optimize my own blog. Some of the mentioned plugins and optimizations I had already in use, a few I added as result of reading said articles:

You could call this some kind of heavy maintenance, so I’m now interested on some feedback. How do you like the new comment plugins? Does the site load slower or faster or did it stay the same? Any reply is much appreciated, especially feedback about the loading time of my blog 🙂

I moved all javascript used on my site to the foot which should reduce the loading time a lot more.
Please let me know if something is now broken 🙂
