Morriss' law(s)

I recently came across a couple of lists of software development laws:
The eponymous laws of software development
Laws of software development

I may or may not have publicly stated Morriss' law:

Every site/program/app attempts to expand until it resembles Twitter

See Facebook, Skype, Confluence

However on one of those lists I cam across:

Zawinski’s Law

This law addresses software bloat and states…

Every program attempts to expand until it can read mail. Those programs which cannot so expand are replaced by ones which can.

I was going to state Morriss' second law, which is like the first one, but has "until it has Stories", but I think there's Morriss' greater law at work here, which is something like:

If they copy you, you're doing something right.

 There's probably a better way of saying it though.
