If self-signed certs were the norm and no PKI infrastructure were in place, no matter how poor, MITM and similar attacks would be widespread.
But plaintext http, which is the norm now, is better?
In some ways, plain text is better than a false sense of security, obviously in a pragmatic way it is not. But, why use half measures when the business case for rudimentary security is so easy? You've already done 90% of the work implementing SSL. You can get an entry level signed cert basically for free. One case of fraud due to MITM is going to cost more than a signed cert. You can always upgrade your cert level if there's a business case for it. It's a case of penny-wise, pound foolish. Don't cheap out when you are dealing with money that belongs to someone else. Certs should only be the first step.
@nefai i know you're being sarcastic, but that warning is coming from twitter. I wasn't getting that warning until I enabled that script
@alfred we know, this thread is not directed at glbse in any way any more, at least I hope it's not, they've taken a step. too bad the www subdomain throws a hissy fit, though Nefario could always just create a re-direct.
