Ask HN: Thinking on creating a blog and need help (platform)

Hi everyone, i'm thinking on creating a blog and need some advice. It will be a programming based blog. I don't know if it matters but i'm primarily a .net developer. First, my main question, is about which blog platform to choose. Here are some of my requirements: 1. Really low maintenance - I already have enough to do. I don't want to add to the trying to maintenance on software/hardware a blog system unless its a no brainer.

2. Custom Domain Name

3. Ability to customize look/feel as much as i want including custom CSS

4. I don't know how possible it is but i would like the ability to migrate from one platform to another if i so choose. So if i choose blog platform x i can switch to blog platform Y if i like.

5. Ability to put whatever scripts i choose like google analystics.

6 Different Comment Engines - I don't much about it but i do want users to be able to leave comments so maybe Disqus?

Of course since i'm just starting i don't know what else i should be looking for.

I've looked at a variety of them (its hard to choose with so many) like wordpress, squarespace, silvrback, Ghost, Roon, Ect... One of them i looked at is "Postach" was pretty cool in that the publishing platform for your blog was evernote (which i'm a big advocate of) just don't how great it is.

I don't mind paying for a platform as long as its worth it. ($5-$6 a month).

On an aside when creating a blog do you recommend just using your main site such as "mysite.com/blog" or do you recommend creating a domain specific to a topic? For example i plan to do some post about Angular. So would it be better to create a domain like "angularisgreat.com". That kind of limits you when you want to talk about something else though :P.

Anyways, any help/advice would be greatly appreciated.....
