The website doesn't have any real-world experience.  I would
like to know things like 'Filesystem X has much better
meta-data performance than Filesystem Y', or 'Don't try using
netcdf files on Filesystem Z, because the performance will
be awful'.

Discussions about real-world use will help users get through
the marketing fluff to find out what is really going on.  Not
everyone has a chance to test every single filesystem before
choosing one.
