Themes this week

We count the projects builders share on Reddit each week. A project is counted once, in the week it first appears in our sources — that’s not necessarily when it was built or launched. Because some weeks are busier than others, we compare each topic's share of all projects, not raw counts, so a busy week doesn't make everything look like it's growing. “Up 70%” means a topic is taking up 70% more of the conversation than before. In the Sep 28 – Oct 4 edition, the last 4 weeks are Sep 7 – Oct 4, compared with the previous 8 weeks, Jul 13 – Sep 6; the last 12 weeks are Jul 13 – Oct 4.
