Everyone predicted twitter would crash and burn within months of the layoffs.

It didn't.

Anyone who has worked at a large company knows that 1/2 the staff there is stuck keeping the lights on because it is easier to hire a warm body than fix tech debt.

I've worked at companies that are literally 10x more effective than other competitors in the market purely due to good engineering practices.

Even within large companies, you can have orgs that are dramatically more effective than others, often due to having to work under just the right set of resource constraints. Too little and no investments in the future, too much and it becomes easiest to build fast and hire people to duct tape the mess that is left behind.

You and the poster above disagree about the state of Twitter.

Twitter had been a growth company, it was early/missed the market with Vine, but was showing ad growth.

Now, as a private company, backed by the world's richest man, sovreign wealth funds, and banks that have written down their stakes, it has different economics than a tech / growth company.

It's ad revenue is now, not in the ballpark of the fortune 500 or trendy Instagram ads, but somewhere between reddit and sin site markets.
