I see that more and more people are use Wiki-makeup and removing HTML tags. But I like to use HTML-tags. Is there, from a technical point of view any difference between the folowing notations;

== Foobar == (h2)Foobar(/h2)

Wiki markup is preferred because a good Wikipedia article is not only useful to read, but easy to edit. We want non- compter nerds to be able to easily edit and add to topics in which they are interested. Also, I still have a long- term plan of eliminating most HTML for security reasons.

I also treat Wiki markup specially in the software in a few places; for example == Foobar == will cause a page to be ranked higher in a search for "Foobar", but the equivalent HTML tag will not.
