There is plenty of digital work and discussion in this forum including two dedicated digital forums, one for techniques and one for hardware. The only thing that is being ask of the members is that they have LF in common.
If you want to talk about what you do, lets do it. You have picked a very convinient comparison, yet I would like for you to show me any digital camera that can obtain the same quality I get with my 8x10 with one shot none of this stitching.
You want to talk about stitching and big files, I can do the same thing you do and get even bigger files. Choosing the proper focal lenght I can photograph sections of a scene, scan the 8x10 negatives and end up with a file in the gigabit range.
You want to talk about HDR, I can shoot a negative for the highlights and one for the shadows and blend them together, in the computer or darkroom.
You are way out of line accusing this forum of being a subset of APUG just because it does not wish to change it's focus and cater to the taste of a few members who insist on talking about dslrs.
