I think it depends on the type of other people you have on the team. Truth is, in regards to the team I own, the most active posters on my forums are people that have more than one player on the team(myself, and all of my GMs, plus my brother-in-law).
Now, I have players on other teams where there are A LOT of active posters, mine just doesn't happen to be one of them. They all respond to PMs and don't go inactive(or leave their guy on Relaxed training when they're going to be away), they're just not big on the forums unless I ask for direct response.
From a gameplanning standpoint, having 1-4 close agents own the entire team is the best way to go. It's not a coincidence that most of these types of teams(that aren't just starting out, or are out-leveled drastically in their league) are winners. When you own that many players on a team, you're really invested in making sure they win - so you're more likely to have agents that boost and equip their players. Not to mention you can assure you're all on the same page when building players, in terms of how the team is going to run it offense and defense(since the best team owners will tell you it's about builds and how your players compliment each other in the style of team you run).
From a forum standpoint, yeah RR is a bit dead - but most of the banter that goes on there is a lot of helpful stuff. There's a lot of knowledge in the GM positions on that team(you'll notice that each of the GMs owns and/or GMs quite a few team...and has at least a few high level players).
I don't know that I'd like to own my entire team like LT, but I'd definitely like to only have a max of 5 agents own the entire team. It helps with accountability and responsibility. Plus, when I want mindless forum talk...I just go to the league forums or the main GLB forums.
