This sums it up pretty well, but I think it's essential to detail the Manatsu no Yo no Inmu connection given how much that community crosses over with and has fundamentally influenced Cookie from the beginning and made it what it is. The sheer volume of parodies and otoMADs, the extensive tag 'genres' thereof, acronymisation of the actors' names, direction of the later dramas etc. are all direct results of the 'homo' community latching onto Cookie due to its commonalities with Inmu (bad acting/bouyomi, melodrama, generally poor production, etc) after the tag vandalisation of the original video. It's a big part of why Cookie is considered to be a mostly separate entity to Touhou rather than just another derivative work - the constitution of the culture that shaped it and exists around it is very different.
The actors are significant as well given that so many of the injokes and characterisation of the 'characters' in parody material and the later dramas is derived from them, their online presences, personal idosyncrasies and various bits of real life information dug up by elements of the community, as well as forming the moral quandary that is probably the barrier to entry for a lot of people.
