Thanks for the details, they do help, a lot.
At a specific level: I agree with and understand your expectation - the problem is: How do we balance that expectation, with the desire to keep the already indented subthreads, as flat as possible? E.g. if we always indented, then if we click "reply" to each other a few more times, in this subthread, we're back to the problem of "every discussion becomes a diagonal"...
The only obvious solutions (afaik) are:
- to add an extra placeholder "box" at the end of each subthread -- However that would create a very cluttered UI... :-( (e.g. adding 2 more boxes, for flat-level replies, at the 2 subthreads in Topic:Sgopn8j210lt00xw )
- to let editors choose their indent level for every comment -- However then some of us will just apply our old habits and preferences, which would lead to an inconsistent and even more confusing style!
- the current system, where the bottom "reply" link (in the main thread, and subthreads) creates a flat-level response, but where any earlier "reply" links create an indent.
At a general level: Personally, I like reddit's long diagonals! Other people prefer the stackoverflow style, with specific indent limits, and font-sizes for each indent-level. Some other people prefer the completely flat style used in bugzilla and many bulletin board style forums.
The indenting style used here currently, is hoped to evolve into something that works best for all of us, whilst avoiding the limitations or flaws of the other 3 main styles. I believe (personally, as an editor) that it does have the potential to become something the communities can all accept (and adapt to), with a few more tweaks. But I'm not sure what those tweaks ought to be.
Sidenote: Each of the new ideas (innovations, experiments, etc) has to get feedback from a handful of people (because there's an understandable reluctance to "just change everything, about sub-feature [x]", based on only 1 or 2 negative responses...), so you adding your comments/perspective/individual-phrasing here, really is immensely appreciated.
