If there were an alternative most of us would be gone already probably. At present however Bitcointalk has a monopoly position. And the crypto scene shouldn't belong to only a few, but to all of us.
There is no monopoly. You are free to post in any other forum or chatroom, or just close your browser and hike the Appalachian Trail.
But I'm getting a feeling that it's not posting, reading, or otherwise participating in this forum you're concerned about. Am I right?
