Implementing pattern language in a Loomio group?

Does anyone have experience in developing and using a pattern language, as lovingly developed by Chris Alexander in the 70s and taken up by some schools of software developers? And implementing it as a structuring device, in a thread-based, dialoguing medium - a BB, Loomio?

I’m in a project - a Loomio discussion across a mix of topics within a broad practical field - which could warrant a pattern language approach, to evolve some kind of overall design or analysis framework grounded in the constructs emerging in various threads. But if there were only 50 patterns, say, is that 50 threads?

I’m unhappy with so many threads, in addition to (say) the same number of threads of ad hoc topics arising from whataver it is that group members decide is worth posting on. Endlessly scrolling threads down the home page isn’t a good UI experience? Is a (pinned) 'thread of threads’ the answer? Even so . . . dozens of threads on the home page (continuation pages) is inelegant?

On the other hand, a single thread with 50 sub-threads would be pretty messy I think.

Is a subgroup (open to all) the way to tackle this, nesting the pattern stuff one level down from the ongoing ad hoc flow of deliberating? No. The subgroup threads are visible in the main group, right?

Am I talking about a usage that calls for some other technology altogether - a wiki perhaps? A wiki wouldn’t be closely integrated with the world (the Loomio group activity) that was throwing up the pattern-categories. Is there experience here of integrating across Loomio and wiki?
