little rant

My problem is mainly when, because of sofware, database (or anything related to IT) architecture impose its way into how the real world works.

For example, imagine Deutsche Telekom. If you have a contract for both mobile phone and internet at home with them, it's completely reasonable that they have different internal systems and thus your name is stored in different locations.

Let's say you change your name. You call Deutsche Telekom (mobile) and tell them that you changed your name, the lady tells you that she updated your name in the computer and all is good. Next month you get the invoice and it shows your old name.

My question is: is this acceptable?

Growth Hacking

I know about the existence of Growth Hacking and I know that as a StartUp one of your goals is to, well, grow as much as possible.
I also know about the existence of promotional posts, and how they can benefit both writers and companies looking to reach audiences.
What I didn't know, is how low some companies can go in order to promote their business for free.
Without further ado, here's an email I got yesterday. Let it speak by itself.

Hi Jose Tomas,

We’d love to see what tips you have for social media marketers. 

We would like you to create a post on your personal blog where you share
