He asks, we answer. Twitter (TWTR) - Get Report CEO Jack Dorsey -- who also serves as the CEO of Square (SQ) - Get Report -- opened up to the Twitter world in an effort to find out what its users want to improved.

@Jack asked, "what's the most important thing you want to see Twitter improve or create in 2017?"

The questioned has generated more than 6,500 replies and according to Dorsey, the most requested feature "today & always," is for an edit function. Users want to be able to fix their tweets, be it factual or grammatical, without having to copy the entirety of the content, modify it slightly, re-post it, and delete the original post.

Surely the company can figure out how to do that, right? Dorsey says it's something the team continues search for an ideal solution. Zooming out a bit, the four most requested "themes" for Twitter encompassed abuse, editing, topics and interests, and conversations.

I would say this is a good move for Dorsey and Twitter. The company has struggled mightily with its stagnant monthly active user growth and even saw prospective buyers walk away from the property for some of the issues mentioned here, (mainly abuse).

With that said, addressing those issues with its users may help lead to a more favorable platform. If all goes as planned, improvements from Twitter will hopefully lead to increased user growth.

Shares of Twitter closed $16.30 Friday, down 0.6%.

Back in September, SpaceX had a rocket somewhat mysteriously explode on the launch pad in Cape Canaveral, Florida. Thankfully, no one was injured in the explosion, but it did raise a number of questions for the Elon Musk-led company.

In fact, Musk even called the explosion "the most difficult and complex failure we have ever had in 14 years."

While it took a few months for the company to sort everything out, it appears SpaceX is getting back in the saddle. Or should we say, back on the launchpad.

Sometime between January 7 and January 9, SpaceX is expected to gain clearance from the FAA to launch its Falcon 9 rocket into space. The rocket's payload has already been loaded and now the company is in wait-mode.

The payload consists of 10 satellites for Iridium, a satellite-communications company. Despite the previous setback - which the company believes was related to frozen oxygen bursting a tank of helium during fueling - the company still expects to press forward and win additional contracts.

Should it do so, it may not be long before Musk has two companies, the other being Tesla (TSLA) - Get Report , that need his undivided attention.

Shares of Tesla closed at $213.69 Friday, down 0.5%.

Another week, another Apple (AAPL) - Get Report iPhone rumor. But with 2016 coming to an end, what better way to finish off the column for the year?

The expectation is the company will "supersize" the iPhone next year, according to Forbes. 2017's phone will be Apple's 10-year anniversary for the iPhone, causing expectations to rise for many fans and investors.

The latest leak suggests there will be three screen sizes, 4.7-inch and 5.5-inch models -- like the iPhone 7 and 7 Plus -- are expected, along with a larger, 5.8-inch device.

The largest of the devices would use an AMOLED screen, while a TFT-LCD panel would be used for the two smaller phones. Many also expect, at least for the largest phone, to have the screen that goes up to the device's side edges.

The source also says expectations are for 60 million to 70 million units of the largest device to ship in 2017. 

That, to me seems like an awful lot. First, consider that 65 million or so devices is already a lot to move between mid-September and December. Then, factor in the fact that there are two other models below that device that will ship too.

If that works out to be true, it will be a serious boon for Apple and its investors. Plus, given that type of demand, one could reasonably expect that strength to carry over into 2018.

That said, it could be an overzealous estimate too.

Shares of Apple closed $115.82 Friday, down 0.8%.
