There are so many different posts and ideas it's too difficult which to choose to quote ... so, this is more of a general response.
I completely (like 100% completely) understand the arguments that this bitcointalk forum is a significant and important aspect of the current marketing and spreading the word about DGB. One of the dangers of online communities is that they become isolated echo chambers. They isolate ideas rather than connect and spread them.
It's relevant for DGB - and good for DGB - that we have one of the best and most prodigious altcoin forums in bticointalk. And, the previous comments are right on track ... that having a great forum here on bitcointalk helps DGB by encouraging like-minded people to get involved.
Also - less important - but also - there's a time factor. I'm busy. I'm sure you're busy too. More forums and discussions means more time.
However, I also think there's a place and reason for both. Having the primary DGB forum be here on bitcointalk reinforces the idea that DGB is subordinate to BTC. In reality, at the present moment, that's true. DGB is currently subordinate to BTC. BTC had a head start ... so we don't yet have as big a community, or as many merchants, companies, etc.. I believe that someday we will ... and even more, I believe that DGB has the potential to emerge as a true alternative to BTC ... not just as a subordinate. In order for us to achieve the goal of developing DGB into a true alternative to BTC, we need to start building the infrastructure to be independent - and, a dedicated forum is part of that necessary infrastructure. It's not the only part - but it is part of that effort.
I know that HR has done - and I'm sure will continue to do - great work towards providing support discussions in
http://asistec-ti.com ... maybe some of those will eventually get cross posted, linked, etc., as they are here.
There are also other possibilities and benefits in the dedicated forum ... things that haven't yet been considered, like an informal marketplace for trading, or selling goods within the community. There are just so many possibilities.
My only real criticism is that I'm not a huge fan of "simple-machines" forums. There are better, more interactive, and interesting forum templates. But, beggars can't be choosers. Because I have neither the time or the expertise to develop an administer a forum, I'm on board with whatever.
We agree it is very important to keep the discussion going here on BTC Talk as this is our #1 source of new users and attention. However, this site is a single point of failure and we are definitely in favor of having a DigiByte specific forum to begin sprouting our own two legs to stand on for the long term.
We will begin posting both here as well as on DigiByteForum as well as more technical stuff on HR's forum. We like the idea of having different ways to come together as a community if anything should happen to one particular website or entity. After all, this is a decentralized digital currency. We have always envisioned our role diminishing as time goes on and DigiByte takes on a life of its own.
