An interesting thought from Keith Rabois on Quora:
To be truly successful on the Internet, you need to build something that becomes one of seven sites that a large swath of users will regularly use
I think this is a great way to evaluate companies one is thinking of joining, building or investing in.
Initially I wasn’t sure on the significance of seven, so I did some googling. Turns out that seven (plus or minus two) is a “magical number” in psychology initially cited in a paper by George Miller of Princeton University. Sometimes known as Miller’s Law, it argues that the number of objects an average human can hold in working memory is 7 ± 2.
While I haven’t used Rescue Time in a while, I’d be curious to look at its data set to see how regularly individuals’ top seven sites change and what are the key prompts: changes in lifestyle? Fads? New technologies? Job related? I imagine for most people there are 2-3 websites that will rarely change (ex: your preferred search engine, likely Google), but as you move to sites 5-7 I’d be interested to know more about turnover.
