Favorite thing about SaaS?

Thanks @ninastepanov for adding me to B2B SaaSy!I'm a self-employed (aka freelance) b2b saas copywriter who works with startups in Silicon Valley and Western Europe, primarily. I love my clients, and I love what I do.My favorite thing about saas is that I get to work with lots of smart, humble people. Also, I really love the trend of very powerful tools having really simple, consumer UX.Anyone care to share their favorite things about working in saas? And also what you do?
I love the reach of SaaS and the ability to have longer relationships with customers :) It's the greatest feeling to know your product is sticky and is something that adds value to someone's life!
