Does This Technique Rob You Of "Link Juice?"

[robvegas626]

Hi Warriors. Looking for some quick advice:

When I post a link to my blog -- let's say I post the link in a forum, or on a social networking site -- does it rob me of any "link juice" if I shorten the URL (using TinyUrl.com or another link-shortening service?)

Basically, does Google treat a "shortened" link the same way it would treat a regular long link? Does it not matter? I want to make sure I get credit for every back link that I create.
