The EFF has a pretty good post on the move to make HTTPS closer to the new normal on the web. It’s hardly normal yet, but it’s improving. Already some of the bigger sites on the internet like Google, Facebook and Twitter are serving up HTTPS for almost everything. They do it for security as well as performance (SPDY).
In the longer run (few years from now) I wouldn’t be surprised if the majority of web traffic starts moving over HTTPS. This will not be well accepted by many institutions including all governments, but it’s certainly better for people, especially those in nations who restrict speech and rights the most. We’ll also see a lot of legislation to only use encryption methods with known vulnerabilities and back doors. I wouldn’t even be surprised if some countries try and break the web by using alternate means of encryption similar to what South Korea did years ago. Obviously fighting this is going to prove important.
