Steam recently updated to make it way easier to switch between accounts. It used to be you had to authenticate every time, which was a pain with Steam Guard. Now there's a Change Account function which won't invalidate your authentication token though it does seem to sign you out until you switch back.

I use that to ensure I'm not advertising certain games to the world.

I mean, that’s a good one. But the problem for me is that I already have a few special games, and even without playing them they would show up on my profile if I ever set it to visible.
