Could you please explain the syntax of the URLShorten function that appends the shortened URL with a custom word "howoldplanet" ?

Yes, I tried executing the following command but it did not produce correct output.

URLShorten["http://blog.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution", "LeibnizsDreamAI"]

But, Thanks for letting me know that its available only for special accounts.

Code-Golfing Tweet-a-Program: Martin Luther King's age in years and days on other planets if he was living on them! :-)

AssociationThread[{"yr","days"}->(Now-=[King bday])/#]&/@Dataset[PlanetData[All,{"OrbitPeriod","SolarDay"},"EntityAssociation"]]

Martin Luther King age on other planets

Interestingly, Martin Luther King would be 364 years old on Mercury but only 182 days old since one solar day on Mercury lasts about as long as 176 days on Earth!

I'm not the golfing sort, but this is still pretty short:

Dataset[(Now - DateObject[{1961, 8, 4}])/# & /@ 
    PlanetData[PlanetData[], "OrbitPeriod", "EntityAssociation"]]

A very nice try. With my counter it gave exactly 100 characters:

And actually we do not need pure function there and Map, devision is listable:

Dataset[(Now - DateObject[{1961, 8, 4}])/PlanetData[PlanetData[], "OrbitPeriod", "EntityAssociation"]]

Very impressive code! thanks for sharing. I can only make it one character smaller:

Grid[{(f=PlanetData)[],(Now-DateObject@{1961,8,4})/f[f[],"OrbitPeriod"]}]

by using the @ rather than []...

Thanks, @Sander! I just realized I could easily turn it into tutorial on making microsites. I added some stuff to the post. I hope more folks will be adopting cloud interfaces.
