OK, first I'll admit that I only read this thread up through page 2, then I jumped to page 4 and saw a bunch of bold and yelling, so let me just put in my 2 cents, calmly...
Personally I agree that TBC probably should have put up a notice that they would be out of commission for awhile, but I also know it could be something beyond their control. Every once in awhile I hear sometimes on the news about shooting in Atlanta and so on, and it makes me worry about TBC occasionally. I suppose it *COULD* be that they simply can't get to the website for God-knows-whatever-reason. I doubt it, but it's possible.
It's also possible that they're just monitoring their site traffic to see what happens when they disappear into thin air. Does it drop, does it start spreading out through the older toons, etc. They could be doing statistical studies on that.
I actually was surprised to hear how much they've acknowledged the Wiki and its users, because I had seen an interview once where Mike had said he pretty much stopped looking at H*R fansites when he saw someone saying they've jumped the shark, and he realized that no matter what, there will always be some people who are unhappy, and there will always be whiners. (I suppose we really know that now.) Why bother having that tugging at you? Why bother listening to such whining as what Rose started with in page 1 on this thread? He got a taste of what people like Rose had to say, and he didn't like it...so he stopped listening and started distancing himself from fans.
I don't think it's that they think they're "all that." It's just that they have lives outside of H*R.
And yeah, maybe they are growing a little tired of the H*R universe. I think what Rose was talking about in how they'd been lax on emails for the past year is that, honestly, at least for the latter half of '05, most of the emails really weren't so funny. (I started trying to help out by sending in an SBEmail, and then in parentheses below my email, threw out a couple of ideas on what wacky stuff they could do with it.) Strong Bad has become the star and I know TBC didn't really like that, so I've kinda excused the email-lax-ness as being their effort to bring Homestar back to center stage.
I came and hunted down this thread because of my dumb thoughts about "maybe they're dead" and all that stupid crap.

Wanted to come and see if there was any news, because I was legitimately worried about them. Still am, a little. But geez, I sure didn't expect to see people screaming/whining/fighting over all this...
Just calm down, people. We'll hear something, eventually.
