Svg _should_ be better because every modern browser supports it and you 
can easily put it into an html document (even without javascript) just 
like you can put a png or jpeg into an html document.  You cannot do 
this with ps or even pdf so they are nonstarters.

However, most web blogging/social-networking software seems to support 
them to the same degree that browsers support displaying postscript 
files.  You've got to get in and change settings, and that's not 
possible if you don't own the server (as on a forum or social networking 

In this case, I think it's probably best to allow exporting directly to 
a common image format like png.  Not because it's pixel-exact, but 
because you can throw it into any forum on the web _today_.  And that 
sucks because it punishes people who are vision impaired (not scalable 
and no descriptions of content).  But maybe I'm being cynical and we 
should just use the right tool for the job and write detailed, 
user-friendly guides for how to make one's Wordpress site seamlessly 
support svgs.
