"New" hehe. Definitely fresh, since HTML 4.0 has been around for about 8 years. :p
If by "commands" you mean tags, specifically those introduced in HTML 4.0 (ABBR, ACRONYM, BDO, BUTTON, COL, COLGROUP, DEL, FIELDSET, FRAME, FRAMESET, IFRAME, INS, LABEL, LEGEND, NOFRAMES, NOSCRIPT, OBJECT, OPTGROUP, PARAM, S (deprecated), SPAN, TBODY, TFOOT, THEAD, and Q) then yes, I use a good number of those on a regular basis (abbr, acronym, col, colgroup, fieldset, label, legend, object, optgroup, span, tbody, tfoot). The rest I just never have a need for, or are deprecated/disallowed in the flavor markup I happen to be working in (usually XHTML 1.0 Strict).
