It started out as targeted towards very tech savvy users (i.e. most HN users, including me), but recently they added a feature where you can manage the computers of your friends and family through their web site, which I am doing for my parents and brother. Just yesterday I got an email saying my mom installed the "AOL Toolbar" Firefox extension. I asked her if this was intentional, she said no, and with 1 click, I disabled it. I'm not affiliated with it in any way, just a happy user (although 90% of the time, I don't think about it)
