Similar in concept, yes. Your HP ( Hive Power ) gives you voting power. The more HP you have the more your vote is worth. For example, I up-voted your comment with a 20% vote and it added 0.010 Hive to the comment. As you get Hive you convert it to Hive Power.

Here's a tutorial on 3Speak that will help.

Good place to start... you should sign up on 3Speak as well. Kind-of like Hive's version or Youtube(no censorship though).
