The 1% rule, or how many people actually participate in UGC
It's an emerging rule of thumb that suggests that if you get a group of 100 people online then one will create content, 10 will "interact" with it (commenting or offering improvements) and the other 89 will just view it.The information I've been waiting for. Hurrah!
It's a meme that emerges strongly in statistics from YouTube, which in just 18 months has gone from zero to 60% of all online video viewing.
Further insight is always welcomed.
