You talk like you've never been in a chat room.
Chat and forum are just 2 different things.
Then you could also say it's the same as voice messaging or even why don't you just go out and meet physically if you wanna talk.
Of course - tecnically - you can talk about the same things everywhere, but in fact you cannot. Conversations will turn out completly different on forums and chats.
And I explained my point about Messengers.
I don't say we must have a chat. I'm not the one to decide that anyway. I just think it would be cool and useful.
But I also think it would be hard to make a chat that is safe and has all the filters that make us able to moderate it easily.
Because of course you're right, it would be hard to moderate.
But not impossible. It'd need the community to help, and they would help.
They could make screenshots and report people who act inappropriate.
And I'm quite sure that some of our moderators would also pretty actively watch (and probably use) the chat, just naturally, because they're interested.
However, I don't think it's ever gonna come. With only one coder there'll always be more important things to do on this website. And the bigger this site grows the more of his time it will eat up.
So it's just play of thought.
