Exactly. I could go download the source code (or at least something like it, I'm not sure how much the github repo matches what is in production), and plenty of sites exist which have done this, but without the users it is meaningless.

If you really want an alternative, convince Musk to do it (or bless yours) and tweet it out. Even then I bet it would take years to match Reddit, and it may or may not ever actually exceed it.
