This has been my go-to placeholder site for the best part of a decade. Not because it necessarily works the best, but just because I always remember it.

For me that site has been Lorem pixel. I thought of it as soon as I read the title. Haven't used it in a while so not sure if it is any good now.

Nevermind, it is down. I just thought that the name was pretty cool and always remembered it.

It works for me here?
