Since you seem to be mostly active at Stack Overflow, the main (and essentially the only) difference you will probably observe at Programmers is absence of debugging help questions.
Moderators at this site were given a guidance to quickly delete such questions and as far as I can tell they happily follow this recommendation. Also, community over here is quite unwelcoming towards debugging questions so you may notice many of them quickly closed at score -3 and lower and deleted by 20K users even before moderators intervene.
As for bikeshedding / beat the strawman kind questions, there is not really much difference. I spend quite a bit of time in SO close queue and it looks like such questions are posted to SO at about the same rate as here and standards of both sites have nothing to do with this.
What looks to you like more encouragement here is misleading impression.
The only reason why more of Programmers questions of this kind get and stick in hot questions is that system has special adjustment 1 that pushes Stack Overflow questions out of HNQ list after few hours while Programmers questions, just like all other sites, stick in the list for days.
- For readers who may be not aware of that, purpose of hot questions is established pretty firmly: this feature is there only to show network wide audience entertaining / interesting questions. Those interested can refer MSE for more details on that: What is the Goal of “Hot Network Questions”?
For the sake of completeness you may also notice that Programmers get a bit more of project management questions than Stack Overflow. But as far as I can tell there is not much of a difference really, probably because these questions tend to be better handled at other site (PM.SE).

1 If you're interested, special adjustment mentioned above is explained in more details here. Official reason for this adjustment is to prevent SO questions dominating hot list but this is nonsense, ignore it. If they wanted just to avoid SO domination, they would implement the adjustment differently.
There is a parameter in hotness formula that controls just how to limit amount of questions from single site and tweaking this parameter would guarantee desired limit for questions that can enter the list. Instead of simply changing this parameter they picked an indirect way that makes SO questions leave hot list faster which apparently was the main purpose of this adjustment. The reason they wanted that was to avoid too loud meta complaints when SO questions stick in the list ("croissants" probably scared them).
Programmers also complain about HNQ and we even delete worst of such questions but this site is too small and SE management doesn't give a damn. About 2-3 months ago Shog told me that they are perfectly happy with the way how hot questions work and they don't plan for any changes in that (indeed why would they now that they shut down complaints from the only site that was big enough to force them change).
