There should be an exemption from the Captcha for users with strong passwords. And if this spreads maybe we can just annoy everyone into good security practices.
I use RSS pretty heavily via Feedbin and Unread on iOS but I do sometimes wish I could view my feeds in a curated format akin to a magazine or newspaper rather than a flat undifferentiated list. There probably isn't a big enough market for it but I would love to see more experimentation in feed reader design instead of just cloning the UI of email clients.
One solution could be to very prominently highlight auto-filled fields especially if the standard auto-fill attributes are missing. That might at least help some users avoid submitting info they didn't intend to.
