Ignoring non-papers claiming to have solved a problem is a good crackpot-avoiding heuristic. What isn't even written up is even less likely worth reading than something with only a few citations that is written up.

If that were really what was going on, not status games, then getting a link to the blog post from a couple of known folk of good reputation - e.g. Nick Bostrom and Gary Drescher - would be enough to tell people that here was something worth a quick glance to find out more.

Now it's worth noting that my whole cynicism here can be falsified if this post gets a couple of links from folk of good reputation, followed by genuinely somewhere-leading discussion which solves open problems or points out new genuine problems.
