This just in: an in-development webapp with WebSockets, Shared Workers, and WebRTC integration turns out to actually be "ancient" because it's being managed with subversion!

Then you live in a very small bubble.

I suppose Firefox is ancient too. They use Mercurial canonically. :-(

So does Facebook... My company also uses mercurial - I know plenty of people that prefer it over git - but there is no github equivalent for it.

There's bitbucket. It also has free private repositories.

It never reached the mass that github has unfortunately.

Why does that prevent you from using it?

For personal and company sources we use RhodeCode - so we have both Git and mercurial. I was mentioning github because it is the closest thing to social network for open source.

Well obviously you should just be using Chrome.

Lots of people use and prefer mercurial.

I learnt git when I started college and then discovered Mercurial when I started contributing to Firefox. It was painful at first but after some really good reading of the Mozilla Version Control Tools docs and the Hg Tutorial by Joel Spolsky and some blogs regarding the Mozilla contribution and coding workflow I started liking Hg better than git.

Mercurial has a more sane way of referring to commits and traversing the history. They now also have different kinds of branching models. You can even maintain multiple checkouts of a repo using a single clone which is great and saves me from having to checkout branches when I want to work on another feature. (Imagine checking out 3.5 mn files each time you wanted to change branches).

In, my opinion, Mercurial scales better but suffers from the unintuitive names and lack of enough people talking about it.
