That's an interesting point! I didn't do much clever here, other than sessionizing the conversations (there's a code sample in the project) to try and capture full conversations rather than disjointed snippets.

My group chat was pretty asynchronous at times, and very fast at others, and the character of conversation is very different in a fast-paced chat versus an asynchronous one so I think this actually would lead to improvements. That's a great idea.
