I don't have a problem with the co-existing in one forum, I don't find the commercial builder's stuff that interesting so I tend to gloss over it or not read it at all. However, if it's a design I like (RIM springs to mind with that slotted headstock, mmm), then I'll give it a look.
I am more interested in the home build type stuff, the problems and the workarounds, but each to their own. This is probably because I am a hobbyist with the wrong tools and a quarter of the talent of these commercial builders. Otherwise, I'd be one of them. Maybe one day. Have to improve that turnaround time somewhat though
I don't think there's a need for a seperate forum for commercial builders. Read what you like, don't read what you don't like.
