If you want an example of it in action, you can go to a deployed example of my app at http://pygm.us/kzXSwSRV with the log-in admin//password. I haven't gotten around to letting people change their settings, but you can use the button in the sidebar to see it in effect. If you apply the CSS in one of the threads, you may see why I find the font weight to be a bit on the heavy side. But to each their own and all.
Of course, now that Instapaper supports the typeface, you should check it out in it as well, if you have an iOS device.
Oddly enough, it shows up less bold on a non-windows machine.
Eulexia is an SIL-OFL one that is thinner too. But I haven't worked on the windows font smoothing with that one yet. :-/
