Not necessarily, for example your "Learn python in 10 minutes" post appears as a PR0 page, thus it won't outrank your competitors. Keep in mind that this could be just a temporal glitch and might get fixed automatically if/after your page is assigned a higher PR.
You mentioned that you've set up redirects from the old site to the new one, are you sure that your content doesn't appear twice, using different url's? (ks.net/node/1 and ks.net/tutorials/First)
This will be penalized by Google.
Also your /tutorials url redirects back to the main domain, is this by accident?
