There is a poll going on at the macromolecular modeling blog "What is
your favorite molecular viewer?"
http://rosettadesigngroup.com/blog/284/what-is-your-favorite-molecular-viewer/
PyMOL is currently at the lead, but it might not stay that way, go
ahead and show your support (or choose one of the other viewers if you
like them more) but most importantly drop a comment as to why YOUR
viewer is the best.
Disclaimer: for fairness, similar messeges are sent to the other
competitors mailing lists as well, but we like yours the most ;)
