I think unfortunately it was the inevitable effect of a sub growing too big. Once that happens than the topics of post start to widen to the point where it becomes harder to maintain, especially when there will inevitably be multiple posts of the same exact question, which understandably can frustrate the current subscribers. For example, you reach a point where you start getting the same "What is the best programming language out there?" every couple days and it can get slightly annoying.

I'm not saying I disagree with you, in fact, I'm a beginner programmer myself. I just wanted to put my two cents in as to possibly why Reddit structured the subs the way it is.

I have a Raspberry Pi B+ that's been sitting idle on the shelf for a little over half a year now...been trying to get my lazy self to setup a custom thermostat controller for a mini fridge that I converted into a kegerator. Maybe another six months and I'll eventually get started :P
