Here’s a good example of unnecessarily negative. 

There’s valid feedback here—you’re not doing a good enough job highlighting all of the developers in the ecosystem / perception of picking favorites—without resorting to a bunch of drivel.

You wouldn’t speak like this to someone you’ve never met in-person, so why do it on the internet?

I consider myself a courteous person, but I have fallen into thoughtless personal negativity with tweets/casts many times. It definitely takes discipline and practice to not do it, and I feel a great sense of shame if it is pointed out to me. I’ve learned that a lot of people, unfortunately, are incapable of shame and empathy altogether. Everything about computers, social and news seems too elevate and promote anti-social actors, if not outright celebrate them. Follower count is not a measure of one’s character.
