I don't like the negative vibes I get from http://www.downforeveryoneorjustme.com/ instead giving tip how to stay up it's purposed to say if website is down.

It's normal that companies die. What advice would you give them?

'is it down for everybody or just me?' is a neutrally-framed status reporter. The 'vibes' I speak of are the way in which 'Dead Yet?' is, fundamentally by its name, presumptuous (in my opinion). Therefore I don't think you have a great analogy there but I do see your point that my 'feedback' point was perhaps a bit too general — it would just be nice to be able to review a startup (a small disqus comment thread on the page, for example) rather than just pointing the finger at its deadness.

I don't personally have generic advice off-the-bat for company-wide failure avoidance I'm afraid.

Don't die.

Thanks! This advice helped my company survive bad times!

Negativity is an important part of not getting trapped into a life of propagandizing.

It doesn't come from a place of negativity. As I mentioned elsewhere, it can show how resilient a product is as well. A community for startup support is probably outside the scope of this site (and done much better elsewhere), but what would you like to see added?
