>Some subreddits are OK like /r/sysadmin. However I find that many communities suffer from a snarky mentality. People who thinik they know everything responding negatively or belittling people who ask questions instead of just answering it. I haven't described it well but I'm sure you know what I'm talking about.

When you put together a bunch of soulless people, it's going to devolve as such. You do have to consider for a second though it's not about negativity or belittling but rather finding the answer.

If I post a thread and ask 'How do you improve performance of threading in python?' You might get a couple people who want to help. You likely won't get the true answer of GIL. Overall the thread will fail.

If you post a thread, 'python threading sucks, doesnt improve performance.' You're going to get 50 people with PHD level answers explaining in depth how you're wrong. You suddenly have your answer.
