I use word press, and mars edit for my blog/website creation. Ther's also drubel, or how ever it's spelled, but I'm not a drubel nerd. so can't help with that.
I do recommend wordpress though as it is almost unbreakable. and believe you me I've thrown a bunch of stuff at it. lol! If you want to see a site I created go to my portfolio.
This was created with wordpress and actually redone as something happened when I upgraded, but that was probably human error.
Good luck and be blessed.
If you want something that is easy to use create a account at http://wordpress.com and put your blog there. It's not as elegant as a wordpress hosting site, but it does nicely. I have and use it for stuff when I need it.
Sadly no there is not, but yeah I do use the wordpress app for iOS when I need to post something on the go. I also do the email thing and edit it later. Both methods work, and work quite well.
