It definitely helps, but if you're trying to keep up with the latest security, you'd be susceptible to Logjam (due to DHE-supporting ciphers in the default TLS 1.2 list).
There's the Mozilla SSL Configuration Generator which helps with the madness, but they still aren't keeping up with the latest recommendations.
This is a much more accurate than the old "Locks keep honest people honest" saying.
If you consider yourself an honest person, ask yourself how many times you've tried to open doors to random houses as you walk down the street. If you found it unlocked, do you rob the place?
If you need a lock to keep you honest, you may want to reevaluate your values.
While the ideal flow/funnel is to go from persuasive copy to signup in a single visit, I've often found myself going back to a site/service multiple times over the course of months before actually signing up.
It's probably part of the multiple touch points marketing idea. You may really like a service, but have to wait until you actually come across the problem the service is solving before committing to the buy.
The point being, I think it makes sense to have a sign-up button on your landing page (for return visits) AND in your copy (for first time visitors).
EFF is great and I would encourage anyone to donate/join. If you get a chance to attend, they frequently speak at the DefCon conference in Las Vegas, NV (http://www.defcon.org) and field digital rights questions.
They also produce useful info for anyone concerned with digital privacy like the "Surveillance Self-Defense Project". If nothing else, it's gives some perspective on the complicated legal state of data security and communications.
I hear this reasoning all the time -- that your desire to keep X private is null and void because some fringe Y case would expose you. The world isn't black and white and privacy isn't binary.
There are already privacy protections for doctor/patient and attorney/client, so clearly a legal precedent has been set in those cases -- why not others?
The comic book example, just because the source knows who you are doesn't mean it's for them to plaster your picture up on every internet site and telephone pole.
