My Final Guess
Pattern (@Henrique Valle but in singular)
The Prefix of the modern Age "E" (@1848, @Astralbee) in a boxy Cage
Me and my friends refers to a "." and the "t" that will show up in the third Stanza. The box with rounded ends are parantheses which leaves us with
[e](.t)so far (@Henrique Valle and @insert_name_here)
is his friend minute,second,year (@Astralbee again)-> time ->t set free which brings us to our final regex pattern
Getting the word
if we use the pattern on the whole poem we end up with "p att ern" so i guess i missed something for excluding spaces in the poem and the answer is "pattern"
News (also works for 'Information')
News are often displayed in boxes for example on twitter/facebook or in emails. Interesting news spread aroundAs already suspected my second stanza interpretation wasn't quite right but got the whole world within secondsjob done. The boxy cage could also refer to a newspaper boxintended solution would've been "a-z" or simply a monitor / phone screen. According to google we're also in the "Information Age" right now.
The News are displayed"A-Za-z" in posts (boxes) on a screen (another box), or in newspapers which are often
[A-Za-z]in boxes too. News also make communication better because a conversation without information/news is pretty boringbox with rounded ends
The friend set free This is Timeour capture group which shows up in popups and notifications to notify/alert people about the new news before they're "old news". It couldnow also refer todeals with the newspaper Times which can be bought at shopstwo spaces i encountered. Complete Pattern: / newspaper boxes until they're out of stock/spent
And for the hint:
I'd say the plan is to spread the news which wouldn't have worked if you kept all the news for yourself/together
IP-Address in my Phone/Router/PC makes my messages fly at supersonic speed
And 2. My two previous guesses
Inside of that box i have messengersNews/email-programms that display addressesInformation and you add an address to a letterAddress
At Last 3can be found in the edit history. They didn't contribute to the final answer and make this post way too big.
Not sure on that one i'm guessing the "friend set free" is referring to a date in a message and the "alert someone before we're spent" to the ipv4-Addresses (which are running out)
