do you use xhtml ?
 

The xhtml dtd is supposed to be the new standard for web pages. (implements html tag equivalents under xml).
Are you using xhtml ?
or do you not really care about "standards" as long as it looks ok in the browser?
I've been using Quanta Plus. This and other html editors dont seem to have focused on xhtml, the old html conventions seem good enough.
What do you think?
