Hive / Power and resources?

So...Pretty new here, or catching up as is the sloth way. Can anyone help with how Hive works? What is power and resources etc.

I'm sure there's some great info out there already, i find the community tend to be more helpful with tips and tricks though.

What's the best way to maximise potential for Blogging? Should i spend time liking / commenting on other posts? Does my "upvote" power affect my posting power?

Any other hints for utilising Hive/ Peakd? Do Tags have a big impact? What about the description?

So many questions, hope y'all can help! Thanks in advance!
