You’re right that stickies can become outdated. So if the group went the sticky route then either the moderators or other volunteers would need to monitor, add to, delete, comment on the sticky content. So clearly that is ‘work.’ Also the subjects for stickies would need to be chosen judiciously – so we don’t choose subjects that are likely to change frequently.
Some content might be timeless, like the importance of giving an honest review and what that might look like, do’s and don’ts, what to expect of a platform like Airbnb, what is the responsibility of the Host who’s running the business, need for a co-Host, that kind of thing. Or as @muddy points old threads about kettles, duvets, stain removal could either be left open or – I’m adding this possibility – put in a stickie.
If the group wanted to go ‘the sticky route’ only recurring topics would become ‘sticky subjects’ and they wouldn’t be ‘the last word’ but maybe the first place a member would go before asking the group. Th sticky would also be a place, ONE place for that subject, that a member could link to in a response. [Now we might have multiple valuable threads on a single topic.]
I agree that there are pros/cons to the sticky approach. I just might have raised a sticky wicket.
