Lemmy is the only social media platform where I have an account. No Facebook, no Reddit, no LinkedIn, etc. From time to time I do read a post on Reddit, when it comes up in search results. When you have an obscure gaming or Linux issue, Reddit can (unfortunately) still be a treasure trove.

a lot of European countries have a policy of 5 years legal residence -> permanent residence/green card.

I would like to stress that rules vary (wildly) between countries. In the Netherlands for example you’ll probably need a sponsor, e.g. a partner, employer or educational institution to qualify for a residence permit.

Ensure you familiarise yourself with the rules of the country you want to move to and don’t expect things will be about the same in other EU countries.
