To Fork or Not to Fork

I’ve been working on a new blog and I keep running into the same question, so I figure I’ll pose it to you, my loyal readers (umm, I think, I actually have no idea who reads my blog and I’m OK with that). Should I start a new blog for just technical nerdy web bits or keep everything together? I’ve been itching to write longer articles on topics and I feel limited by the current layout (which I love for entirely different reasons and don’t see changing in the near future). A long article about CSS doesn’t really fit in half a page.
What do you think? Should I start a new blog or just tweak this one? Do you read this blog because you’re my friend and we know each other in “meatspace”, or for some other reason?
