Blogging as a means to tackle publication bias?

Today, I was watching the following talk on publication bias:



Many negative research results are not reported: not only in the medical field, but in other fields as well: even knowing that trying to apply a certain method or technique on your data won't work, could by times mean a few days/ weeks of work saved.

That reminds me of the first TEDxDelft Salon talk I attended, on how we should value tools and other ways of reporting failure and successes in science.



With that said, I was wondering if blogging can help us move towards a world of science where all ideas can be discussed, and not only our successes. I do understand a rant on your blog because an experimental setup isn't working doesn't have all the background and depth that an interested reader might need. And at the same time, maybe the interested reader/fellow researcher might not be aware of the fact that he can find this information on some random other researcher's blog, so we might need to work towards a tighter, better linked network of research blogs?

So far for putting an idea out here - how do you think we can avoid trying and failing at something another researcher failed at previously but didn't report?
