Blogging independently?

Greetings everyone... I hope you'll forgive me a not-quite-40k post. I've got a poll up that I'd like some feedback on. The long and short of it is that I've been invited to write for a 40k agglomerate site. They shall remain nameless for the nonce. Check that. During the time writing this, I've managed to get invited to a second one... Hah!

I've got a decent number of followers here. I'm also not writing for profit, hits, pseudo-fame, or some misguided Pygmalion complex. I write to get these things out of my brain and on "paper". It helps me be a better player. If publishing them helps the next guy, so much the better. It also gives me something interesting to do when I'm bored at work. But as the wise Lao Tzu says, "A wise man knows he doesn't know." I'm not the platonic ideal of an armchair general... I miss things, make mistakes and am ultimately human. One of the best ways I've found to mitigate this is by having others read my ideas. Thus having a larger audience is good for more than just the ego boost.

Now, there's hundreds if not thousands of 40k blogs out there. I'm not really doing anything that someone else isn't too. Maybe I cover it a little differently, with more math, or just my own little spin and models... but there's still a lot of background noise out there. The blogs I see with any regularly high followings fall into one or more of three key groups.
a. Star Power. Typically these are older and more established blogs doing some sort of "guru on the mountain" thing. I have this rep for Eldar on Warseer, but certainly not on the blogosphere or other sites... nor am I sure if I want it. The role tends to be aloof and unassailable, dispensing nuggets of wisdom to the unwashed masses and immune to reproof. It kinda stifles free debate, especially if the author wants to categorize things into black and white.
b. Blogfeeds. Groups like FromTheWarp help a lot to be more than just talking to myself. One of the big things I like about FTW is that Ron is all about external reference, high bounce rate, and just covering his basic costs. If he happens to pick up some extra traffic or commissions, that's just a side-effect. This cannot be said of all the feed or rings out there... Still, with almost 500 members, distinction is difficult to achieve.
c. Agglomerates. These are a central site on which several authors post, joined because of similar locale or interest. This has the advantage of screening out the detritus posts, sharing out the work, tapping a broader spectrum of talent, cross-pollination between authors, and theoretically sharing to a larger audience. There's the downside of pressure to perform, content uniqueness, and conflicts of interest... such as if there should be a profit and if/how it gets shared.

So my thoughts come down to this:
1. I can say thanks, but no. I stay here, do my own thing and see what comes. This doesn't really increase my audience, but I also avoid a lot of potential headaches.
2. Join and put all agglomerate specific articles on that site and my other stuff here. I get the bigger audience, but I might be scrambling to keep this as anything more than a "my models" blog, especially if I join two or more.
3. Join and post agglomerate articles there and here. It probably wouldn't drive traffic here, but would get that wider audience idea. Of course, it might mean having to stay on topic a little more...
4. Join as an 'honorary' author... which is to say, do my own thing, but allow the site to harvest any content they feel would be agglomerate appropriate. This would mean no pressure to post as the decision of "appropriate" content is up to the agglomerate editor rather than me.
5. Something else I haven't thought of?

Cheers and thanks for any feedback!
