Most of chosen posts are good, but i wouldn't choose post three. Anyway, Dev & Tech board could use more merit source who have better technical knowledge, so i support your merit source application.
I am one of the most active members on the Dev & Tech subboard. I have been posting there for about a year. And although it accounts for 4.66% of the merit distribution
DdmrDdmr's statistics, I suspect most of it is going to its subboards. Unfortunately the stats don't offer more granularity to confirm this.
This statistic
https://public.tableau.com/profile/ddmrddmr#!/vizhome/shared/MX3XSCMGR show more details, but AFAIK it also include Dev & Tech child boards.
I'm not really sure how many Dev&Tech - not global - merit sources there are, if they even exist.
AFAIK there's no merit source which focus
only on Dev & Tech. But i'm the most active/frequent one, where 56.99% merit send to Dev & Tech board (see
https://public.tableau.com/profile/ddmrddmr#!/vizhome/shared/FJ8D3H652).
