Ask HN: Which currently free services you use would you pay for?

Draw.io/diagrams.net

Gmail. If that can guarantee support from google.

That's called Gsuite. And yes you can get living person on the phone in my experience.

I know G-Suite. I meant regular gmail.com without custom domains.

Twitter. It's a fantastic user acquisition channel. I don't know how I would have gotten early users without it.

But twitter already has paid ads and tweet sponsoring.

Metroretro if the pricing is reasonable (unlike conceptboard)

Gravity
