the first post of the 2010s//first post of the this decade

[Treecko]

PC has lived through 3 decades (2000s, 2010s, 2020s) and almost 20 years old now. Some of you have been here since the beginning but most of you have been here since the 2010s. What was the first post of last decade (2010s) and the first post of this decade (2020s)

My first post of the 2010s was my intro post and my first post of the 2020s is this one cause I haven't been active since December lol.
