Yes, I thought this was (likely unintentionally) insulting. I rarely use urls unless it's a known site. Especially since I'm Canadian and the TLD isn't always predictable.
And on a phone, it's usually faster to google 'hacker news' or even 'hack new' if I'm lazy, than it is to type 'news.ycombinator.com'. (Yes, I'm horrible. And no, I don't want to bookmark it and make it too easy to come here....)
