Reddit is another example where they've broken the mobile browser experience, to send you to another app. Arguably broken, but in different ways.
Oh, absolutely. One example: You want to connect with someone, and it'll throw up a dialog box on whether you want to add a note, with two buttons "Add Note", "Send". If you now decide that you don't want to connect after all, or want to look up something before composing the note, and close the dialog instead - it still sends the connection request.
