Some thoughts:
1. I don't think the site needs to mimic bitcoin.org, and in fact I prefer that it doesn't. I'd like Bitcoin Unlimited to appear fresh and exciting. A return to the original vision for Bitcoin.
2. Now that someone mentioned it, I do find it odd to have Satoshi Nakamoto's name three times side by side (I like all the quotes, however). Not sure what to suggest...
3. Under "Our latest work" it appears that everything is listed twice.
3.b. Also, could the link to my fee market paper open up the PDF version instead? Until we get the equations looking proper in the HTML version, I'd rather hide it. The link is:
http://www.bitcoinunlimited.info/downloads/feemarket.pdf
4. I'm not sure I like how the navigation menu folds when you reduce the window with. This happens at even moderate window widths:
Also, it appears as though the aspect ratio of the Bitcoin Unlimited logo is altered (i.e., the circle is an ellipse!).
To kill two birds with one stone, I suggest we use Adrian's idea of writing "unlimited" in small underneath the word "bitcoin," but keep
@Graphics saturated orange coin. This will reduce the width of the logo and help with the navigation menu problem too.
5. Before this goes live, it seems weird to have the same picture float in as used for the background. Also, the background picture is too zoomed in. I think this needs to be refined.
6. Rather than "strength in numbers" how about something more inline with our goals: "A payment network for planet Earth" or something like that.
7. Social media icons: do these even work? I would prefer to omit them entirely unless someone is actually going to keep them up-to-date.
