Wikipedia might have problems, but at this point larry sangar is just desperate to try and reinvent wikipedia with him at the center to stay relevant. He's started an excessive number of wikipedia like sites with some variable changed, some pretty silly like the cryptocurrency one where it was intended you could vote for what the truth was using your crypto wallet (they never actually implemented it but what could possibly go wrong in a plutocracy?). He's just desperately throwing stuff at the wall praying that something sticks.

Like all things, there will probably come a day where wikipedia is disrupted by some new kid on the block, but i highly doubt sanger will be at the center of it.
