No data yet. Mostly vocal support from a majority of mining pools and the broad industry at this point. That's why Classic has the most chance to get activated.
Vocal support is useless. You've stated the same for XT and look what happened. There even was a signed letter announcing its support. What a joke.
With my limited understanding, I've come to really like SegWit and some associated options. Is there anything we can do to help - take up mining in a small way for example?
This doesn't help the development process though. The easiest thing that you could do and show support is to set up a few full nodes.
Coinbase already did...
Why am I not surprised that this evil is on board with this?
