What Mercurial DVCS hosting would you recommend for a small open source project?

I'm looking around for free Mercurial hosting for a small-scale open-source project.
If you've ever used such a service, who is doing the hosting, and would you recommend them?

I know SF.net can be set up to host HG repos, but it looks like a lot of trouble (for the benefit of having a big, known, service that's unlikely to go down anytime soon).

There's also the list of free HG hosts right in Mercurial's official documentation, but I'd like to hear from those that actually got down and dirty with it :-)

From stackoverflow

• BitBucket is certainly the most popular. I've experimented it for while, then I jumped into git.

  Aaron Maenpaa : +1 I've been very happy with both bitbucket and Mercurial.

  Steve Losh : +1 as well - BitBucket is great. You get repository hosting, a version-controlled wiki and a great issue tracker for free!

  quark : +1 BitBucket has a *very* nice interface.

  kitsune : +1 Bitbucket rules

  idursun : Bitbucket also lets you to create a private repository in the free plan

• I use Bitbucket for a bunch of Open Source projects and am very happy with it, too.

• Have you considered using Project Kenai? I have an account but have not hosted any projects there so I can't comment on the quality of service.

  Chris Upchurch : Oracle has just announced that Project Kenai is going to be discontinued: http://www.oracle.com/technology/community/sun-oracle-community-continuity.html

• For small code examples and if you don't need a wiki and stuff, you could try http://freehg.org else you should give http://www.sharesource.org a chance. Or just use Mercurial as intended by publishing your source decentralized to other developers using the integrated webserver for example :).

• sourceforge.net just added Mercurial, Bazaar and Git support.

• Bitbucket is the best hoster i have encountered so far.

  The service is fast and rock-solid and the staff is very fast at addressing any itch you might have.
