We have had good conversations in the past about the different functionality and use of different forms of media. My own way of expressing this depends on ephemerality or duration of relevance:
- up to a few days: best on something like WhatsApp
- from a few days to a few weeks: best on a forum
- more than a few weeks: best on a wiki
These aren’t hard and fast divisions, of course, but I’m happy to explain my take on this and why it makes great sense to me. The different functionality is adapted to the different contexts. And there are so many examples where you can either see the functionality working well, or see it misused.
Reaction emojis can serve as a useful bridge as well, which weren’t in common use until a few years ago. A reaction to a forum contribution is naturally ephemeral, but if expressed as an emoji it doesn’t clutter up the main thread. So…
I agree that it doesn’t make sense to have “the wiki” as a forum thread, but I don’t think this is the intention. Talking about the wiki makes sense to me as a forum thread.
On the other hand, updating the wiki directly from the forum makes no sense to me, as it would confuse the different timespans of relevance and ephemerality.
A wiki, as I see it, exists long-term partly to enable progressive cross-linking, as more relationality becomes apparent. Ideally we would be able to functionally cross-link different wikis, but no one to my knowledge has implemented that functionality.
What could indeed be useful, and what I see as the value in the position expressed by @rufuspollock , is to be able to take forum material and easily cut and paste onto the wiki. Here on Discourse I really like the simple functionality that allowed me to cut and past the above two sentences along with the source metadata, allowing future readers to go straight back to the source to see it in context. I wish it were that easy in a wiki, and indeed between a forum and a wiki.
So, one practical project I would love to see funded and implemented is a suite of software that recognise the functionality that is appropriate at different timescales for different purposes: both for encouraging collective conversation and the related sense of community, and for the creation and maintenance of a knowledge commons that both serves the hosting community and acts as a learning resource for others with an interest — potentially drawing them in.
One extra point added later … … one of the key factors in usability is the ability for people to understand and predict what will happen when they take some action through the interface; and another obvious one is to provide affordances for actions that are most likely to be wanted. Confusion puts people off in many ways. To be avoided wherever possible!
