I’ve noticed the escape issue and I’m quite surprised the out of the box product, which is many years old, doesn’t deal with it properly. There are quite a few bbpress plugins and mods.
I’m a developer with pretty deep experience in Joomla and WordPress. WP of late has been my platform of choice because of how clunky joomla is, and how horrid it is to upgrade when they change versions. I started bbpress as a test but so many asked to try out the site I ran with it. bbpress is unorthodox in a few ways, and no engine will be perfect for everyone.
