I've got some feedback/tips:

-It's too emotional, i had the feeling you were trying to convince me Blackcoin is superior but the arguments are not technical and structured enough.  A document like this should read like a small manual of a technical product and have that kind of design and structure. 
But it reads like a folder for a place of worship written by an enthusiast of -20 years old. 
I wouldn't use all those arguments of the flaws of other coins too much and let the reader itself come to that conclusion, if it was his choice to come to this conclusion he will cherish it much more.
With all sentences you construct you should think: is this technical or emotional? And in case you have already used the technical information hidden in the sentences then you should scrap that sentence, all information just once.

-Wtf is this reference to myspace doing in a PR doc???

-The first word in a blackcoin PR document should be Blackcoin and not Bitcoin.

-The backbone schematics of the coin are completely missing, amount of coins, how PoW was distributed, the block size and halving time etc etc.


If you want i'd like to help and just rewrite the document the way i see it and then you can comment on mine.  I'd just do it to be be constructive after critisism.
