The main issue is that a lot of the 'off-topic' rules are focused around content that doesn't work on SO. It doesn't work because it's time based - asking 'What is the best IDE for X?' is subjective and changes over time. Yes, that list of answers might be useful and interesting right now, but over time, it becomes more and more outdated and eventually, downright misleading.

There is a reason SO has excellent results on Google - the content is carefully curated so that it's timeless, and editing allows it to get updated where it needs to be. Yes, sometimes good (at the time) content gets discarded, but that's the nature of it.

If you want that kind of stuff, do it somewhere more transient.
