Hi,
</p>
<p style="font-size: 16px">
We're definitely getting more blog posts about Perl 6 since FOSDEM. I wonder if that's going to continue for the rest of the year, or if it's still the after-effect from FOSDEM...

More than anything, participants in the Pull Request challenge seem to want to fix bugs. Put your buggy dists on github! :-)
