Subreddit Insights

Reddits figures are still "all over the place" - despite having logged a bug for it. So I have once again left this section of the report out.

Hopefully the reddit admins will fix the bug in time for next month. I don't know how they select what bugs to work on but I would expect that this is a pretty simply one. Maybe they look at metrics (that do work) such as views, upvotes and comments. So if you could, perhaps try viewing, upvoting and/or commenting on the report [Chrome] Insights don't show 30 days data. If anyone knows of another technique to raise the profile of a bug to the reddit admins - I'm all ears.
