They’re imr enduron powders my Main audience, and I try to shape the content for them, and perhaps add a pair nuggets in there for the greater Innovative crowd (like During this post, I identified the non-linear marriage and introduced up the concern about primer balance).

That’s entertaining for me, however it just restrictions the value you increase to your shooting Group as a whole.
