Obviously a fun sort of question, as it's highly dependant on your niche etc, but a lot of people seem to throw around relative traffic terms without quantifying it which is very misleading imo.
Men in my country at least are just generally more interested in tech. A big population of males who are interested in tech will naturally lead to a heavily weighted male populous of proficient tech people. I don't get why this is sexist it's just fact. I don't see much that needs to be fixed.
If there is discrimination in the hiring process though, yes that needs to be addressed. However that's not the angle the article is taking.
Hiring a woman because you don't have many women in the work place isn't optimal.
Would people be happy for banks to use the same security for your account? Because that's what people seem to be arguing when they say it's perfectly safe/secure. This is in regards to the obscure URL being the entry point to the account not to do with BC itself.
I'm not sure why my comment got down voted so much, my point is if a obscure web address is the only line of security it is terrible, especially as they recommend you to bookmark the address in your tool bar. The point is it might look great and secure at first, all it takes is a small mistake from one of many angles and it's done for. Examples of mistakes, people posting their urls, people being tricked into posting their urls, shared computers with bookmarks, the webmaster accidently installing a sitemap script which indexes them all etc.
The tossing your physical wallet out the window analogies are tired and false. When does your wallet ever have thousands of dollars in it? Some naive BC users had huge % of their net worth in BC then got punished for it in various ways.
Yikes, no security except the obscurity of the address... I'm not sure I would be comfortable using that. I know the search space is huge (~10^28) but there are so many other implications.
I find it hard to believe companies pay Google $55 per click and that is in any way profitable for them. There must be more +EV opportunities out there for advertising. But I'm probably mistaken as usual.
