No. Serious projects do not care about bitcointalk anymore because this forum has clearly turned into a sad little joke with people that are forced to bash any new competing currency/project for fear of losing their investments in other coins. Anyone with even half a brain can make that out.
If you haven't noticed, ethereum devs too don't seem give two hoots about this troll city and I'm not surprised at all.
Torr, I've always thought of you as one of the more credible people in the NeuCoin forum. Not that that amounts to anything, but, disagreeing and asking relevant questions does not equal trolling. People seem to think that any question they don't like is "trolling".
My exposure to bitcointalk is this thread and I've read through (but not responded) most of the Garza/GAW/Paycoin scam thread. I agree, there's likely some trolling, as there are in all Internet forums, however, there have been many valid questions asked here that haven't been answered. I'd like to see some answers to the althouse stuff posted the other day. Instead, it was completely ignored. That should concern people about NeuCoin.
Also, over the Summer, very little response to what seem like useful questions, and then all of a sudden, when the beta was released, Sandrine comes here and announces. That post was a bit of a turnoff because it started off somewhat insulting and it seemed like she was gloating about delivering something. Something that was late.
As far as Ehtereum goes, I haven't looked at the threads here about it. However, I will say this. I'm a somewhat technical person and I attempted to install the command line tools, GETH, and ETH on various different computers with different OS's. Not one install worked. I attempted to troubleshoot for a while and got bored with it. I know very little about Ehterum, but perhaps things like that is why they're no longer responding here. I can't see something like that doing well long-term if they're not able to make it more user-friendly.
