I just had one single thread where I documented my decisions, build progress and answered questions that was over 1,000 messages and 240,000 views in this forum. It was chronological and stayed all together. It sometimes got off-topic but that was what the members were interested in at the time.
I have another RV build coming up. I've looked at creating a blog website, Instagram, or a Facebook page, this forum again; or maybe nothing. Website blogs are difficult to maintain or just one more thing to bother with and I have had a history of private websites going away not of my volition. Instagram to me is confusing, Facebook pages are easy to set up and convenient for you friends on Facebook, easiest to promote and easiest I think to post visuals. I don't know about this private forum's audience reach but it is Class B centric.
Creating individual threads for each build topic in this group I think would be chaotic and difficult to manage and follow.
