I assume they are rhetorical questions? Otherwise you are asking the wrong man/old f*ck.
No dude it is not rhetorical, it was real question
Example : Every time I am reading news, let's say I read about Basketball, it says #Euroleague became the No1 trend on Twitter. I go to mafakin Google Chrome, I open a Google.com page, cause I am an oldschool jerk, and in the search field I type "#Euroleague" and then i am eating crap by zero or weird results.
You dont have WhatsApp, you dont have Twitter... do you still write letters by hand?

Hahaha... Dude I told ya those staff are evil!!!! Jokes aside there are tons of reasons i still don't use those apps.
First of all here in Greece almost everybody uses the other app, Viper or Viber, wtf is called. Every time I have the same strange conversation :
-OK I am sending this to you via Viper
-(me) no mofaker I don't have Viper, I have 4 fakin different email addresses to send me whatever you like.
Then I don't like how those apps are messing with my main phone SMS and calls apps. Each time I have tried some, it keeps messing with settings, resulting me sending an important SMS without internet wifi/mobile data ON, and the SMS is pending for a connection to be sent to.
And the final part on this, I understand that living in Ireland or UK or any country of the civilized world, means internet everywhere and access to the community of informations from everywhere, free wifi, 4G,5G,7G etc..
But living in a fourth world outter Rim of the Galaxy, means shitty public Hotspots and wifi internet only at home or mobile data. By my standard monthly mobile package I have 1GB mobile data, but once it is consumed, it costs extra 2€ per day with 3G speed limit, or if I buy a special extension pack, costing 7€ for 700MB for a month. Which is a money grab too.
So I can't rely all time that I will have internet everywhere. I am still counting on my old school phone calls and SMS, which I never consume by my standard monthly mobile package.
As for Twitter I will come back latter with an essay. I think creating a profile for reddit was my limit breaker. On Twitter I don't even know how do you properly read a string of comments below a post or who is posting, who is sharing /retwitting??? or who is replying to whom!!
At the moment, I am training them to evolve into Pidgeottos..
