Also from what I've noted is that when you sign into a secondary account on the main profile's account, Chrome is prompting you if you don't want it to create a new profile for you.

Then again, they have the problem that they think that it's appropriate to open the last used profile if you start Chrome again, which can lock out inexperienced users out of the other profile since they don't know how to get that one started.

For me the normal solution of creating separate profiles in Firefox is to use Firefox Portable and have each profile live in their own directory / installation.

Most people just don't troll on hn all day and don't do personnal stuff on their work computer. We are a different kind. I know a lot of people who are afraid of possibly be fired for logging on their webmail with their work computer.

Additionnaly virtually everybody owns a smartphone which is used for the personnal stuff.

These are still power-users. There are millions of power users out there, obviously, but relatively speaking they are a niche.

So the real problem is that Google forces you to sign in to your browser with your Google account?

You guys don't just use different browsers for this :D?

I've got Firefox, Opera and Chrome and each one has different logins :D gotta be honest, didn't even know Chrome and FF can also do that!
