How can I write complex math equations on posterous using LaTeX? Do they support it or anything similar?

I have mailed their support two times in a row, but there was no response.

As mentioned in this blog post, Posterous is a rather inflexible blogging tool. As far as I know, there isn't any support for what you want to do, and I do know that it would be very difficult if not impossible to do this yourself - Posterous doesn't really allow custom javascript to run on a blog, which is probably what you'd need.

If you are willing to migrate away from Posterous, then I'd suggest you add MathJax to the blog to do this; it's what's used on sites like math.stackexchange.com to render mathematics and works really well.

If you're not, then I think you'll need to do some pre-processing of your Posterous posts to detect LateX, render it, save it as an image, and replace the LaTeX with that image in the post. Not really a nice way to do it, but it seems there's no other way.

  • I've never really encountered anything like 'Posterous is not a good choice'. But, yes it sounds like I have to switch. Thanks for your answer. Aug 24, 2012 at 0:37
  • What blogging platform has most feature on it? Tumblr? Aug 25, 2012 at 22:34
  • I don't know, I suppose it would depend on how flexible and vibrant its plug-in system was. It will always be a trade-off between ease of use (posterous is super-easy, just email your post in...) and flexibility (write your own blogging software and it can do whatever you want).
