I have started a new website that will focus on Alternate Cryptocurrencies: http://Cryptoyeti.com
I only have a few articles up right now, mainly aimed at beginners, but have much more planned.
Right now I have been focusing on Ethereum guides and how-to's to start, not because that will be the exclusive focus, but it is a hot and profitable Alt coin at the moment which I think will be attractive to beginners.
I also have a Ethereum Mining Profitability Calculator up and running: http://cryptoyeti.com/ethereum-mining-calculator/
Let me know what you think and feel free to offer suggestions for improvement or ideas for new content.
