For a newbie, your first post is really impressive. Unlike most people who come to Bitcointalk, you already had solid knowledge about Bitcoin before coming here, while most people who come to Bitcointalk is complete newbie.
My first post is nothing to be proud of. But if you already asking, ok, I'll quote:
Sparkling mineral water and coca cola
It's one-liner reply on 74th page of off-topic thread ''My favorite drink is...........''
Short story behind this post - when I signed up here, I had very limited knowledge about Bitcoin. So, I was a bit afraid to post in main boards because I thought that if I will say something wrong, older members will mock me. But it never happened. Now when I look at my first posts here, it's similar feeling like to look at your own photos on Facebook which were made 10 years ago.
