Yes. I personally prefer hg over git and originally used bitbucket, including signing up a startup I worked at. The biggest problem was that bitbucket made it painful to have multiple accounts (work and personal) so I gave up using them for personal stuff. The startup is now defunct. I did have some unpleasant experiences though, including a security hole (since fixed), which didn't leave me with much confidence.
