In a twitterstorm moments ago, Zillow (NASDAQ: Z) CEO Spencer Rascoff explained why he likes Facebook (NASDAQ: FB) as a company and a stock and tries to emulate them.

1. Tweetstorm about $FB #Facebook. (16 tweets total.)
2. Disclosure: $FB is my largest personal stock position (other than $Z, of course).
3. I bought $FB pre-IPO at ~$30 and doubled down at $20 when everyone thought they were dead on mobile.
4. $FB is the most impressive company and stock in Internet imo.
5. $FB does a few things very well, which inspire me (& @ZillowGroup $Z)
6. $FB recruits and retains great people, bound together by a visionary leader with a BHAG
7. $FB product is totally focused on mobile; desktop comes second.
8. $FB takes big swings, including huge M&A swings
9. $FB prioritizes user experience above all else. *Advertisers follow audience.*
10. $FB benefits from network effects on both sides of its marketplace: users beget users, & users beget advertisers.
11. $FB invests heavily in making ads useful to the user, thx to data, which benefits monetization & user experience
12. $FB is willing to invest far into the future -- no near-term focus on profitability
13. $FB does big M&A which was mocked at the time. Insta $1b, WhatsApp $19B, Oculus $2B. Who’s laughing now?
14. $FB doesn't always succeed, but learns from each mistake (e.g.: IPO snafu; Facebook Phone; privacy & user permissions)
15. I am long-term long long long $FB. And I’m watching and learning from their playbook.
16. $FB Twitterstorm complete.

4/ $FB is the most impressive company and stock in Internet imo.
