> not to mention that nearly all forums use html format. I mean, some people actually type ^, especially technical people since it is a math symbol. Why not replace __ with b closed by /b or === with u closed by /u or '' with i closed by /i
It's a feature, not a bug!
Wiki syntax's purpose is to make it easier to edit and more legible for non technical users, and without people having to learn html.
It also keeps things clean so it is possible to have understandable diffs in the version history.
