I've often wished for a "bookmark" feature indicating how far I've actually READ in a thread.
Right now, "jump to the first unread post" assumes that you always read the thread all the way to the end once you open that thread.
I guess I could use the "Star" feature to mark where I stopped reading, and immediately edit that star so I could find it again, by putting "BOOKMARK" or "###" in front of the star comment.
But, in the spirit of always asking for more than seems possible, it would be nice to have an in-thread button, perhaps on the left-hand menu bar, for "specify THIS post as my last read post".
In Cubits, I would sometimes keep notes - stop reading at the bottom of one page and write down which page was next to read.
>> slogged through some long threads and found that after a while they tend to veer off the subject and then later get back on it. Lots of side trips
I have to plead guilty to a veering approach to online discussions. I try to curb that, especially in any thread that is currently following a specific topic, but "TRY" is the operative word.
Some long threads are candidates for a "Reader's Digest" version, where all the off-topic posts were removed, and parts of posts that were not on-topic were edited out.
If there was some way to get consensus from the on-topic contributors, they could even be turned into articles.
More likely, it might be possible to get agreement that includes agree-to-disagree, or agree-to-have-different-perspectives-or-goals. Then the "digest" would include several points of view and "yes THAT is true, but also ..."
Of course the biggest downside is that someone would have to do all the selecting and editing, even if it WAS possible to get agreement on what was "right" or important to each contributor.
Besides: there is already a good mechanism with all the advantages and none of the disadvantages. If someone thinks "this would have been a great thread if it didn't keep changing focus", they could write an article from scratch using the information they agreed with and considered most important, cutting down the number of words by 90% or more, but keeping what they thought was the "meat".
Or maybe share authorship of the idea with the original contributors.
An Article or Idea has more potential to be like an encyclopedia article than a thread does. Threads are like conversations.
