Since I have gotten into the habit of quoting some of my posts in other contexts, I have started to also archive them using WebCite. One can quote the resulting archive as:
Rzepa, Henry. Quintuple bonds. 2010-04-18. URL:http://www.ch.ic.ac.uk/rzepa/blog/?p=1722. Accessed: 2010-04-18. (Archived by WebCite® at http://www.webcitation.org/5p5BtuzSH)
There is one issue though. Many of my posts expose molecules via a Jmol popup. WebCite cannot archive that aspect; the Jmol applet fails to run (it would be surprising, since WebCite would have to archive a local copy of Jmol to create a new sandbox). Anyone got any thoughts?
