I think the web solved the issues pretty early on. I know if I go to bbc.co.uk that I'll get fairly accurate news reporting. Domain names pretty much solve the identity issue.
How do I know who is accurate and who isn't on twitter? I have no idea who is a real journalist on there, and who is a 4chan anarchist.
There's no weight - everyones tweets are equal in search, which is a good and bad thing, but mainly bad IMHO.
The point DA was trying to make is that new mediums have these kinds of problems & we are pretty good at fixing them. For the internet it was a combination of people/skills developing (eg domain names, brands) & technology (eg Google) that eventually (pretty quickly when you consider that article is just a decade old) fixed this.
That doesn't mean real time search will get fixed in the same way or prove to be useful in the same way. It just means that when any such new medium (twitter, web, cup of tea) arises, we should expect to find comments like yours.
