I’;ve also been hearing a lot about how site speed is becoming an important factor but I have mostly just ignored it as you did. But this post has opened my eyes to it so I am going to implement a caching plugin right now and look into the other things you mentioned. Thanks!
My friend when he was in Germany bought a commie trablant right after wall fell for kicks. He got a crack in it and the damm car was made of recycled plactic and there are no parts. He took a bunch of plastic soda bottles melted them down jammed the molten plastic in the crack spackled it quickly and spay painted it and it was good as new.
