What URL for Tumblr and How to?

First question:
I'm starting a new photography blog (haha it's like my fifth blog on tumblr) and I need a url.
I was thinking something with "shutter" "click" or like "nikon" or "canon" in it. (The two brands i use.)
What do you guys think?

Also, I was just wondering… I always see people with things in the comment section saying: "Boho Blog!" and then it's blue cause it has a URL to their blog. Is this something they manually copy and paste into the comment section everytime they reblog, or is it something you can get? If so, can someone tell me please how to get it?

Thanks so much guys! No rude answers s'il vous plait.

Blogs are dead.

Have you considered using Google Plus with Hangouts as many photographers around the world have? Interfaces with Picasa http://www.google.com/...learnmore/

Photos and videos from your phone are automatically uploaded to your own private album on Google+ so you never lose your memories. From there, just share with whomever you want using
