I and a couple others were discussing the hostililty rampant on most technical forums. So we did something about it, and created https://codethoughts.org/ "Code Thoughts".
It's free. It's friendly. Let us know what you think!
Good luck keeping hostility out of coding discussions! I think we've always done pretty well on that front here, but gumpiness seems to be endemic in developer society!
Yes, well if we can keep ad-hominem attacks out, that's a good start. And politics/religion/sex.
