Research user data

• Is using just Beam user data enough?
  • How many users do we need?
• How can we correctly combine Beam user data with Reddit user data (just comments)?

Interactions could be stored like this:

user	subreddit	count	last_interaction
mygrandma	funny	30	1484349988

• user : user fullname
• subreddit : subreddit fullname
• count : sum of all interactions the user has had with the subreddit
• last_interaction : the last time a user has interacted with the subreddit (Unix timestamp)

Now we can give a higher weight to subreddits that users recently interacted with.

There are still problems with this approach. The interactions count will just keep getting higher, but that doesn’t mean that the user recently liked the subreddit. E.g. a user could have visited /r/marvel 30 times last week and one time this week, the total count would be 31, but the user is obviously less interested in Marvel movies this week.
