let's see what's happening in china. a huge team merely for content censoring is required if your website ever displays any user inputed text. that's why china's twitter copycat companies have to employ several hundreds people(while twitter has 2-digits employees), and quite often make their entire designing / marketing department join the censoring team temporarily.

While it doesn't invalidate your general point, Twitter has 600+ employees: http://blog.twitter.com/2011/08/your-world-more-connected.ht...

update on the numbers, i just searched google and found that sina weibo recruited 1000+ people in march 2011. i was being a little bit too conservative in the first place. cant really estimate how many they've employed since then.

With every next paradigm it seems the content creation gets easier, and the volume is higher. We had blogs, web 2.0 sites, social media sites, and each time the volume increased. I don't think it's sustainable for them to keep this up for decades.
