Yeah, I have some ideas about including different data sources. You have to start somewhere, though, and Meetup.com has a nice real-life aspect to it. My best guess would be that Github and HN would add most interesting data from a technology &#x2F; community popularity and natural language perspective respectively.<p>Question is: how do you connect a Github repo or a HN post to a specific community? Content based? User based? Topic based? The community detection in the real life Meetup.com network is at the very basis of this and for good reasons, so you&#x27;d have to find a way to tie other data to that idea.
