While I have only participated in a quite small part of dpreview (Adapted lens talk) - which means I probably don't have a very good indication of how a really populated, active forum looks like - I'm quite impressed by the amount of activity here, where I'm also taking a look at other areas. It's interesting to see and I feel like it might be a benefit to re-think the whole structure and see this as an opportunity. I'm sure there are several examples but here's just one observation:
It looks like some very interesting long-going threads for sharing weekly or monthly images and giving/getting feedback were hidden in several sub-forums of dpreview (where they originated) despite them having been platform-/brand-agnostic for a long time.
It's great to see that some people are trying to use the inevitable changes to set things up in an even better/more appropriate way.
If this spirit lasts for a while and perhaps there will even be an improved solution for the (somewhat flawed) threaded/flat view of the dpreview forum, I'm personally not going to miss the old place.
