I am playing now the DR since early 2011 and I am gigging with it. I have also posted several Threads on the old DR-Forum, because I initially (and still) believed in a separate forum for DR-user.
But all in all: there are several pros and cons. Let me point out my thoughts to it:
Yes, you can say that it always affects one component (for shure). But this is only half of the (my) truth: I found out that it often affects TWO components. It is very often the POD HD AND either the DTXX OR the JTVXX, because the POD HD is the hub for the Dream rig (it controls also the JTV and the DT-amp). So I found myself sometimes posting the SAME issue on the POD HD AND either on the JTV OR the DT-Forum.
Yes, you can say that with more forums you may loose control of the already existing overload of information. I personally get the new Threads to my E-Mail account, so I am on spot. I don't think that is really in issue.
Another aspect I figured out is that the way I am using the JTV, the HD5000 and the DT50 is different as if I would use it, if I integrate only one of these into another guitar rig. Especially my presets on the POD HD (this is the hub) are not at all comparable to any other presets I would imagine just using the POD HD and / or a DT-amp. This has developed over the last 2 1/2 years. Especially how to control the Dream Rig via POD HD or over the JTV-knobs is something I feel a lack somehow.
Another aspect are new users which are buying the complete DR: clearly speaking a lot of them I think are lost when starting (like me initially). A DR-Forum could be a serious kick-starter to overcome a hard learning curve which it is in my opinion.
Although issues it may affect only one or often two parts of the DR, user want to have a "HOME BASE" - being part of a community of proud DR-user - RIGHT ?????????????????
Finally the most speaking point to me which points to a DR-Forum are the user feedbacks here: PEOPLE WANT IT !
