It turns out the bitbucket issue tracker has a feature - I cannot make it automatically add me 
to the watcher list of all new issues.

So when you create a new issue, I think I get one message about it, and no more.

If there is some other activity on the issue (Stefan answers, Thomas answers),
I most definitely will not see any of it.

So in case you wondered why I sometimes completely do not react to some bug reports, this 
is why.

So much for "advanced" and "highly automated" and "intelligent" bug tracking.
