Decent article. I like the grouping of coins into three broad sub-categories: alt-coins, meta-coins and para-chains.
I have an alt coin newsletter where I share my thoughts on what's happening with alt coins. Feel free to PM me your e-mail if you'd like a copy. I just sent an update last night.
I find
https://vircurex.com/ has most of the alt coins that I'm interested in. However, buying them before they are listed on
https://vircurex.com/ is how you can really make a big score on the next new coin!
