Here's a UX critique, I don't always want to be on my phone. Especially since the "Blah wants to be your friend" opens in the Android browser rather than the Path app. I'm not logged in in my mobile browser, and I don't want to because my password is a huge random set of characters. I'd login from my desktop since I have LastPass, and I can't accept the friend request from the Path app natively. Thus, I have friend requests piling up and I've yet to return to the app.
