Funny thing that you mention about Linux. I used to have a Linux blog where I only used to write about Linux. It was very easy to get traffic, my best months were ~600k and I was making fairly decent money (around ~1500/month), but I was very easy on ads and had to turn down many ad offers even though they had amazing CPM (from Microsoft, Apple and antivirus softwares). I ended up selling the site for 20k in 2008, cause I needed some money for a new project and I was getting bored with the blog. I guess the lesson I learned from my experience is that almost ALL traffic can be monetized. Who knew you could make $1500/month from a linux blog? I could have made more if I took all the offer and pushed it farther. Now that I think about it I think it was a mistake to sell it, the new owner totally trashed the site. :(
