Most interesting presets are for instruments. FX presets are interesting,
but on a per-plugin basis they tend to be less fascinating.
LADSPA doesn't support instruments at all.
The "state" extension for LV2 hasn't been around all that long.

plugin itself has no API to set its state, but any LADSPA's plugin state
was intended to be representable solely in terms of its input control
ports, so the host just loads the LRDF preset and sets the control ports.
(2) LV2 has the State extension (don't balk at "extension" - almost
everything in LV2 is an "extension) which is designed for saving plugin
state in a host and platform neutral way.
I looked into this format, and see it is XML, found some
presets in ~/.ladspa/rdf/ardour-presets.n3
To make it easy to share presets it might be valuable to
have an app-independent way of browsing and comparing them.
We share a lot of music, here, and I hope that presets could
be shared as readily.
It surprises me, really, since without proprietary
pre-cooked offerings, everyone producing music with Linux
invests a lot of time to find suitable plugin settings.
You'd think that open source source community would share
them as well.
