I love using RSS-feed and I wanted to use it for this site too. The problem is that my RSS-Reader does not render Latex so I get the source code of Latex and trying to render Latex in my head is not so easy! Wouldn't it be better if the Latex formulas are sent as pictures so that the RSS-Reader can do a better job.
I am also open to suggestions of an RSS-Reader (for linux), which can render Latex or Mathjax or whatever.
