Any decent blog engine?

I’m new in blogging world. I though one day „why not?” and since then I am tyring to configure a decent blogging engine on my website. I am struggling with templates and CSS so the site will look cool and professional, will be readable and have ability to show C# code nicely… It should just work!

I though it will take 20 minutes to set-up… but on the other hand, what does.

Anyway I am happy it’s all free :).
