I'm a technology dude. Always looking for innovation and improvement. It's a form of intellectual restlessness, not a criticism, not a complaint and not taking anything for granted. I always want the next thing: it's a job requirement. It doesn't mean 'the next thing' is the right move for the group or community. It might not be.
Discourse is a nice solid platform and this is an extremely functional community, from what I've seen. (Well, except for the debate about peer review LOL I don't even know WHAT to call that. JK) If any innovative platform were an option, at the point in time it should be done as an 'add on' side experiment, where you see if it gets traction, so you don't whack the existing successful forums.
Just so no one thinks I'm a wild eyed revolutionary Warrior for Christ (figure of speech, religious people). I'm a Director at a 100m company in New York, so I don't make sudden moves, or recommend them.
