Ask HN: Resources for getting started with NoSQL / Big Data

I've read quite a few articles posted here and else where about Data startups and some tools to work with such data.

Are there good resources out there for beginners to learn more about NoSQL data stores and use case scenarios for each solution (case studies and what not) and for data analysis using the same.

Any blogs that are recommended? I tried taking a look at MyNoSQL blog (mynosql.mypopescu.com) but that blog is nothing more than a copy=paste archive without any insight at all to justify the solutions and what not. Not really useful for someone who wants to get started with such solutions and look beyond RDBMSes ..

Thanks..
