What websites do you visit most often?

[XMC-plMof]

I'm curious which websites and online portals people visit most frequently. Do you mostly use news websites, social media, forums, entertainment portals, or specialized websites related to your hobbies and interests?
 
Personally, I tend to visit a few websites regularly rather than constantly switching between different portals. I'm interested to hear what other people use on a daily basis and which websites they simply couldn't imagine being without.
