Redirect old blog properly

This was in mixpanel as someone who bought http://lostechies.com/jimmybogard/2012/11/07/why-githubs-pricing-model-stinks-for-us/#comment-797532902

But it doesn't redirect properly anymore :(

I can't edit the comment anymore and there must be more links like this linking to some part of blog.gitlab.com
