I work a lot on open wireless networks. All of my important traffic is encrypted (HTTPS, IMAPS, SSH). Some unimportant stuff isn't, but if somebody runs off with, say, my Slashdot identity, I don't really care.
The one exception is Wikipedia. It doesn't seem to do HTTPS. Before I was an admin, I didn't care, but now somebody getting ahold of my credentials could cause a fair bit of trouble. This makes me a bit paranoid about using Wikipedia at all, and inclines me to stay logged out. So in a way, becoming an admin has made me less engaged.
The best solution I've come up with for this is setting up my own secure proxy and then using something like FoxyProxy to selectively route Wikipedia traffic to the proxy. That seems like an awful lot of rigamarole, though, and I'm wondering if anybody has some simpler solution.
Thanks,
William
