Just as people erroneously trust search engines to lead them to the right place, a stickied link to electrum.org still depends on trust - trust the forum admins haven't stickied a phishing link, trust the forum hasn't been hacked and the link changed, trust that electrum.org hasn't been hacked and fake software uploaded, etc. We shouldn't be stickying links because it again leads to a false sense of security. I would however agree with stickying a guide on how to verify that the Electrum version you have downloaded is genuine, for those who do not know how to do it, such as the one linked to from the electrum site itself: https://bitzuma.com/posts/how-to-verify-an-electrum-download-on-windows/. This is a better option all round.
