I'm moving the @rain_capital newsletter to Substack. I want to create a space for some deep thinking about complex and thorny issues in cyber, a bit of VC style reporting, blended w/ the POV of a woman-in-tech. If that is your jam, sign up here. https://t.co/ar789TtTQc

@DomainGang @Azmaldomainer @brandvalley @afternic The first quote I received from Godaddy was $200,000

[Chenxi Wang @chenxiwang]

@DomainGang @Azmaldomainer @brandvalley Godaddy is just a broker. Whoever owned the domain before me set the asking price.

On my way to an important conference with investors today. The first thing I did in Waymo was spilling coffee on myself. Sigh.

Met a founder for coffee this morning.

I got there a few minutes later. He had already ordered me a cappuccino with whole milk.

"How did you know I like cappuccino with whole milk?", I ask.

"That info was in my CRM"

Hot damn, I am impressed.

I see Dario all the way in the corner there, but where is Sam Altman?

[Chenxi Wang @chenxiwang]

@dkulshitsky Many of those issues are caused by CAPS lock.

[Chenxi Wang @chenxiwang]

The CAPS lock key is the most useless key ever invented. Convince me otherwise

[Chenxi Wang @chenxiwang]

@zeynep Is it really unlocked? Still asking me to enter a credit card...

Heard from a hiring manager of a tech company -- 95% of those who applied for their open positions are fake profiles, probably from North Korea. 95%!!

@united The OP link is here: https://t.co/VlUN44BLMk

[Chenxi Wang @chenxiwang]

I published this on Linkedin abt my exp hitting 1M on @united-- 83k impressions, > 700 engagements.

Brands pay good money for this kind of engagements

But it is all free to @united b/c the simple gesture they made

Good customer service doesn't have to be costly

[Chenxi Wang @chenxiwang]

@united The comments on the post are gold -- many detailed their exps with other airlines -- a fantastic thread for customer service folks to mine
