Personally, I don't get what's so special that make people add "360" to the end of a name. I'm not a big fan of those type of names, but there has been a few sales of those names that got decent $$$, which suprised me. Personally, I'm not a fan of those "360" names, but it could have some value, not too sure on the exact amount though.
