Not many sites use https:// but it is the future. SSL has be activated on some of my domains and I’ll be passing along that information and what it’s about to my children. It’s important, now, and in the foreseeable as well as very distant future.
Using different sites it is curious how many do not encrypt properly. On some sites anyone can feel safe to add comments using any login allowed, nice when wanting to comment on a blog anywhere, and multiple options are supplied over an encrytped site.
