Instead of percent difference a more useful stast would be percent change from last month (the difference between the net number of new posts this month from last momth. Also useful would be percent chance from last year. As boards have more and more posts, each additional 1,000 new net posts will have a smaller impact on the percentage of new posts.

Could be interesting, but quite a bit more work
Thats why the Share part of the charts is interesting. The share shows how much weight the posts in a specific child board have in relation to the total number of posts within the analysed local board. That can be seen as an aggregate for the last 18 months (shown by default), but on the Merit Dashboard you can play around and filter by month to see the share (weight) of a child board for a given month. Doing this over several individual months gives you an idea of the evolution in share (but it is also subject to the influence of deleted/moved posts).

For comparison, it would be useful to also see net new posts in the English sections, possibly split up between the main boards and the altcoin boards. In general, interest in bitcoin rises and falls with prices and with prices way down from the highs in 2017, interest has also fallen, and I would expect the number of new posts to have declined from December 2017.

A while back I did retrieve data for all the boards, but without drilling down into the childboards (see Analysis Merit per post per Section/Subsection). The information there was relative to the period 23/01/2018 .. 22/11/2018, and although there is a merit per post focus, the posts contains a link to a Google Sheet doc with that shows the number of posts created per month, much like Ive done here.

On this occasion though (OP), I wanted to focus specifically on Local Boards, and also display as Ive done the first level of child boards (this more detailed). Its rather cumbersome to retrieve all the data, and requires quite a few hours to complete the task (very manual).

A general global overview in relation to BTC price can be seen here:

The following charts shows:
