This is a bit minor, sort of a first world problem, but I thought I'd bring it up. It seems like the way Dave responds to tweets, disables a function that lets you view the conversation. To do this correctly, you ideally have to click the reply button under a tweet, which will cause this connection to be made. To illustrate the difference this makes:
The tweet1 image is from Patrick's Twitter, and has a "show conversation" link. Here shown as "hide conversation" since the conversation is collapsed. Of course, in longer conversations, you can follow the whole conversation with just a couple of clicks.
