We are getting offtopic a little, if you don't store your BTC on our computer, help topic author please.
Sure thing

Homepage: COINMARKETCAP link is sort of broken (only first C works as a link). Same for coindesk.
Can't speak to the accuracy of the history. On /bitcoin.html, SHA256 is not encryption, it is a hash. Might be helpful to mention its basic properties (i.e. indistinguishable from random data, deterministic, one-way (guessing input from desired output is practically impossible). Otherwise, that page looks good.
Page about blockchain is a bit short on technical details (although, depending on your target audience, that might be OK). Uses is good, might be useful to identify examples of cryptos that support each of those uses.
Thanks! I'll get those links fixed ASAP. And thanks so much for the corrections, I'll make a few revisions later to fix the errors and flesh the blockchain/uses pages out as well.
Also, @Velkro, would it have been better if I just posted the url as opposed to a hyperlink? (it's a weebly site) If so, it's cryptocointro.weebly.com.
