I agree with johnbrent, you have to pick your blog url by your own, if anyone suggest you unique name then before you signing up with that name, there is possibility of other may chose it before you. spend sometime on blog sites create a URL that you wanted and start promoting it.
you have to choose it man, but consider few things before:
name should amaze people
name should attract consideration
should be easy to remember for people
Use keywords like guide, guideline, info, technique, tips, expert with seo and blogging. Check the availability with godaddy(.)com. It will suggest you other combination also, if your guessed domain will not available.
