Each Saturday, Farhad Manjoo and Mike Isaac,

Each Saturday, Farhad Manjoo and Mike Isaac, technology reporters at The New York Times, review the week’s news, offering analysis and maybe a joke or two about the most important developments in the tech industry.

Mike: Hello, Farhad! How are you? I just got back from a week of “new hire orientation” for The Times. I’ve been an employee here for 18 months. I guess we run on a slightly different timetable.

Farhad: To be fair, 18 months doesn’t seem like nearly enough time to complete a thorough background check on you.

Mike: Fair. So, I was sort of checked out of the news flow, but came back to a deluge of tech craziness.

Google is doing this thing with a bunch of other tech companies to make web pages load faster on our phones, which is theoretically a good thing. Jet, the online shopping Amazon competitor, killed one of its main business model decisions — to charge for a membership — which seems theoretically like a bad thing (for Jet, at least). And Dell and EMC are considering some sort of giant merger or takeover, which is still in its theoretical stage. Also, I have no idea how to speak intelligently on the cloud — the cloud! — so let’s just tiptoe past that.

Farhad: You forgot about the Microsoft event. They made a laptop! With a screen that’s actually a tablet! I thought it was pretty cool. Maybe PCs are cool again?

Mike: Zzzzzzzzzzzzz. Oh, sorry. I just fell asleep with my eyes open.

So let’s talk about Twitter, a medium in which you and I both do our best work.

The company finally has a new chief executive, Jack Dorsey. He also happens to be the old chief. And, incidentally, still the chief executive of another company, Square, which is in the process of an initial public offering of stock. I can barely clothe and feed myself regularly while doing my job, let alone think about running two companies, so suffice it to say that Mr. Dorsey makes me feel bad about myself.

But here’s a question people behind the scenes keep asking me: Mr. Dorsey is the new chief executive, but he was also on the board for years as chairman (though no longer) and had a shot earlier in the company’s life span to shape and form Twitter in his own vision. On Friday, we learned that he’s planning a series of cost-saving measures, including layoffs. But beyond that, will Mr. Dorsey’s return actually be a radical departure from all the things that seem to be wrong with Twitter — hard to use, niche product, bunch of spam, not Facebook — or will it be more of the same?
